In following the Alder Lake thread over on the Plex forums, it doesn't seem like its an FFmpeg issue. But since AL works with Jellyfin, it sure *seems* like it must be something they're doing.
Alder Lake doesn't work with Jellyfin on Unraid, though. Still crashes when HW transcoding.
Likewise, Plex on Ubuntu now has working HW transcoding. The problem is Kernel + Specific ICR version.
Unraid will crash on Alder Lake if you enable the GPU even WITHOUT actually hardware transcoding.

I am getting ready to do the same thing. My understanding is that iGPU transcoding will still be a problem until unRaid 6.11. So I am steering clear of HW transcoding until then. Others have advised me not to spend the money on a NVIDIA card since 6.11 is near. Although I'm not sure what "near" means.
Release dates are always up in the air, but in this case the problem is already solved, it's just a matter of Lime releasing a version of Unraid with the correct kernel and ICR versions packaged. As this is a fairly major thing in bringing on full support for 12th gen Intel processors, I expect it's going to be somewhat of a priority. I'd be very surprised if it didn't happen (at least with RC versions) inside a couple months.

Honestly it depends on your demands, how many users will simultaneously be running non-direct play streams, and what your current hardware is. If transcoding is going to be seldom, then I'd go with 12th gen and wait it out. If you have users constantly and simultaneously needing transcoded streams, then I'd go 10th gen with an NVidia card. I'm running 2 or 3 simultaneous direct plays, and the occasional transcoding job, and my 12600k doesn't get above 50%. I've also got a Handbrake container running software encoding on all my movies - going to throw in TV shows as soon as iGPU is fully supported (which handbrake might currently support, I just haven't tried it since 6.10.0-rc3).
10th gen doesn't need a Nvidia card. My old system, an 8th gen pentium, could easily handle 12 concurrent transcodes on the igpu, and only met it's limits because the cpu couldn't really handle the audio transcoding. Something an Nvidia GPU couldn't do without messing around with drivers due to the transcode limit.
I really regret having sold it when I built the 12400k server

So does that mean if I go with Alder Lake I won't be able to use Plex, or just Plex with HW transcode?
As he said, no hardware transcoding *for now*. Given that working versions exist for the Plex, the kernel and ICR, it's just a wait till Unraid packages up and tests stuff for the next release of Unraid. Obviously I can't guess at when that will be, but I'd hazard a guess that they'll take this seriously and get the update ready ASAP.

No I am not on Alder Lake. I am looking to refresh my tech since it is 10 years old now (on an i5-3570 CPU). I tried upgrading to 6.9.2 several months ago without hardware transcoding turned on and my system crashed within 24 hours. Tried several times but could not get it to stay running for more than a week. I rolled back to 6.8.3 and it was running fine until today.
Now I am thinking I may need to accelerate plans for the hardware upgrade.
My latest post on the current situation:
Ooooh I understand!
Perhaps you'd be better served getting a 10 series Intel CPU and motherboard instead of Alder Lake? No worries about iGPU compatibility that way but still excellent performance. Very good prices now, too. A 10600 or 10700 would perform extremely well.

It is significant but the tech I have is 10 years old now and I can't update unRaid to any version after 6.8.3. I had to turn off hardware transcoding because it made my system unstable. There are times when 4 cores is not enough.
Sorry? Are you not running Alder Lake? Why can't you run a newer Unraid version?if you ARE on Alder Lake, you can't use hardware transcoding eight now without making your system unstable because, as I said, the current Linux kernel in Unraid doesn't support it.
What's stopping you from upgrading your Unraid installation? My system is running a lot of *very* old tech, PCIe 2 HBA's and the like, and it's working just fine.

Because the iGPU issue will get resolved? Seems like this problem has been around for a year now and I haven't seen any problems reported on NVIDIA.
Because Alder Lake is new. The problem is already technically sorted out, it's just a matter of the correct ICR version and Linux kernels getting pushed down stream. The current Linux kernel in Unraid doesn't support Alder Lake iGPU's properly.
It's already working in Plex for Ubuntu.

Thank you for the reply. I will move forward with my plan to upgrade my current system with an Alder Lake cpu and a NVIDIA graphics card.
Wish that was more reasonably priced without hassles. If you want 4k HEVC transcodes, and no transcode limit... Fairly significant money for capability you already have
-
I installed IntelGPUTop again and Jellyfin, system crashed some 18 hours in *without* transcoding (Plex does this too)

Either I'm very lucky or I gotta disagree. Been running RC kernel for 2 weeks now.
My server is never doing nothing. I'm constantly running encoding jobs in the background on 6 cores, other stuff running on the other 6, often transcoding on the GPU on foreground with 4 plex users. Hope I don't jinx it but it doesn't crash.
You're not disagreeing, you're running the RC kernel. I'm talking about the stock Unraid kernel.
It's very likely a Plex bug though, not Unraid, as mine crashed with Plex running even when not transcoding, but with the driver loaded.

Ah ok it’s not the first time I read that 12400 works may the Igpu is already supported
UHD-Grafik 730 Is also on the 11400 so the igpu support is may better
Nope, stock kernel definitely crashes on the 12400. I think I got two days once, but roughly once a day crashes. Heavy use server, mind you, it wouldn't just crash when it transcodes a particular file, it would often do several just fine.
But hard crashes inevitably.
-
And continuing to document, just in case anyone else has a similar problem in the future.
Still up and stable after 36 hours, that's better than I've managed since 6.10 dropped where I never managed 24 hours. This, with docker just turned off. I'm going to leave it tonight, and if it's still running tomorrow after work I'm going to re-enable Docker, and everything except Plex (where I have a temporary instance up and running on another machine currently). I feel Plex is the most likely culprit, even though it's currently not set up to hardware transcode.
-
Good luck. Mine would crash pretty much randomly, but it'd last for 8-24 hours generally.
Sadly since 6.10 official release it's crashed even more often *without* hardware transcoding or GPU drivers whatsoever. *Sighs*

I should try a 6.9 version, just to see. This current problem started with 6.10.
That's nerve wracking though, because that can't be a long term solution.
-
Well, still crashing daily; often in less than a day. Nothing in logs illustrating why. Shutting down docker entirely and running as a pure NAS for a while to see how that goes. Gotta say, though, this is not a good experience for someone new to Unraid. I'd love more tools to see what's going on and why it's crashing - I mean, if it is something docker, isn't that largely the point of docker? That an individual container crashing doesn't take the whole system down?
-
So, for reference for anyone else who happens by:
Disabled my 2.5gbps onboard LAN, replaced with an older Intel 4-port lan card. Unraid still freezes intermittently, however it doesn't take my router down too. Small wins, I suppose.
Next steps:
Realized I was still running Intel GPU Top (though *not* passing through anything to Plex; Plex has no /dev/dri folder). Because the 12400's GPU is a known source of crashes, I removed that as well. This wasn't a problem pre-6.10, but daily crashes ever since the upgrade have been frustrating.If it still crashes, I'll shut down docker as well and run it as a pure NAS for a while and see.

Enable the syslog server and post that after a crash.
Sorry, I assumed that was in the diagnostics zip.
The most recent crash happened sometime may 23 morning:

Several times since the 6.10 upgrade, my unraid server has crashed, and in such a way as to take my router down with it. I'm attaching both the server's diagnostics .zip and my router's syslog (note: you can see the crashes based on when the dates in syslog.txt revert to "May 4" until the NTP update. Server on eth3 on the router.). This DID happen once before the 6.10 release (though I believe it was on an early 6.10 RC build), but it's been much more frequent since.
I need to restart my router (which returns my LAN to normal) and then the server itself. Of course, this constitutes an unclean shutdown and has caused some issues.
It's a hard crash for the server, though; even with a locally attached keyboard and monitor, not even keyboard lights(numlock etc) work.
I'm kind of at a loss as to what's happening, but it's a new Alder Lake system - Gigabyte Z690 UD DDR4 motherboard, and Intel 12400 CPU. I am NOT hardware transcoding in plex - that causes hard crashes too, but doesn't take the LAN down with it. I'm wondering if it's something to do with the 2.5gbe motherboard LAN? I vaguely remember reading about some issues there?
Any ideas of what's happening, or how to troubleshoot it?

Just adding my experience here. Followed instructions outlined in here with my 12600 and same results. System crashes after a day or 2 of running Plex. Left Plex off and it didn’t crash, so definitely specifically related to Plex using igpu for the transcoding.
Joining the team in the waiting game for a proper kernel update and permanent fix. The price you pay for new hardware on a system built to run on old
Yeah, at first I was confused because I had crashes when nobody was watching anything, but when Plex is detecting intros on new media that is added it's transcodes the start of the file and that can cause it too.

My 12500 doesn't have e-cores but has the upgraded igpu.
What's weird is that other owners of the 12400 report lack of stability. I think flyize runs a 12400 if I'm not mistaken.
Yep, my 12400 crashes too, exactly as the 12600 ones do. Mine is not a -T model, though, just the base 12400.

I did restart it today because of RC8 update but I was running for 30+ days with those settings and not a single crash
So, the overwhelming majority of us have been able to get it working doing just that. It works fine. But we've ended up with system wide hard locks.
It's not about e-cores, as I get them on my 12400 and it has none. Maybe the T version is different? Has a different iGPU? I don't know.
But I'd get (like everyone else) hard crashes every couple days. The frequency *seems* to depend on how busy your Plex server is - mine does probably somewhere in the neighborhood of 30 transcodes per day and many more direct play streams.

Yeah, I’ll be having about 3-5 streams at once. So yeah that actually would be a problem right now.
Does the 11th gen have the same issue?? Or is it only the 12th gen processors.
I love the geek bench scores of the 12th gen but not having the igpu is probably gonna kill me and have a lot of pissed off family members lol
Sent from my iPhone using TapatalkOnly 12th gen. The 11700 is roughly comparable in power to the 12600 as well, so you're not getting a weaker system, and you'll end up with likely a cheaper motherboard too. I deeply regret doing the 12400 thing myself, but it's way too late unfortunately.

The 12600k can do at least two 4K transcodes on CPU alone, which is going to be the same limit that your 8700 can do on QSV.
While there isn't any iGPU support for Alder Lake support right now, you'll still have better overall performance with the 12600k, even with transcoding.Eeeeeh I mean, 2 4k HEVC transcodes maybe. But if he's serving multiple people it's a very different story. My old G5400 Celeron could easily handle 12 concurrent 1080p transcodes and a 4k HEVC transcode. Meanwhile, my current 12400 struggles to manage 4 concurrent transcodes, and starts buffering if any cpu power is used anywhere else. It's a huge problem for me, because the brand new 12400 is wildly inferior in practice to the crappy old *dual core* 2.5ghz Celeron.

Hey everyone,
just following this thread and almost purchased a i5 12600k today to build a new plex/unraid/docker/vm server.
Im assuming the igpu issue is still present, is it close to being fixed or should I still use my i7 8700?
thanks!
I'd *strongly* recommend waiting. If you really want to upgrade now, maybe get an 11700 instead.

Sure, do nothing. Don't install Intel GPU Top, don't have modprobe lines to install the GPU drivers. If you just run Unraid out of the box on 12th gen, and don't do anything with the iGPU then there's no problem at all an 12th gen works very well.
Well, I don't know if the current governer works correctly with P/E cores, as I've got a 12400 (only P cores), but it's stable regardless.
