    [6.9.x - 6.11.x] intel i915 module causing system hangs with no report in syslog (not alder lake)

    Hopefully. Still not fixed in Unraid with 5.18RC5...

    I don‘t understand completely… Do you have a custom Kernel installed on RC5?

    Keep in mind that Kernel 5.18 is still RC and not stable.
     

    As Tom pointed out, Unraid 6.10.x stable will stay on the latest LTS Kernel, which is at time of writing 5.15.38 and 6.11

    Unraid 6.11.x will then have the latest stable Kernel which is as time of writing 5.17.6

    It is maybe possible that 5.18 has became stable and that 6.11 will have Kernel 5.18+
     

    Intel made a real mess here lately and that‘s why I always recommend to make sure that bleeding edge hardware works on Linux before buying.

    I suppose it's possible the dummy is bad...how likely is that though?

    Don't know, if the dummy actually doesn't work and you boot the server up you will get a notification (beep codes usually that no VGA is plugged in) and if you are on the Unraid RC versions you can see almost immediately at boot an issue with the i915 module when it initializes...

    TrueNAS Scale is based on Linux to be their "hyper-converged" stack.

    Ah okay, the more you know... :)

    Then TrueNAS Scale is basically almost the same Kernel version as Unraid 6.9.2 (5.10.28), do they have a beta channel too with a newer Kernel, something like 5.15.38 (latest LTS Kernel) so that you can check that you don't run in exact the same issues as on Unraid?

    Re diagnostics, I've had i915 blacklisted so long it's been a while since I've experienced a crash.  But I did provide diagnostics a few pages back in this thread before it was suggested to try disabling i915 which solved the crashes for me.

    Have you a display plugin in to the HDMI for you iGPU constantly?

    I had a few people so far with crashing servers on the 6.10.0-rc series (of course not 12th Gen because this will be fixed in versions Kernel 5.18+) but when plugging in a HDMI dummy plug or a monitor it solved that crashing.

     

    Please keep also in mind that Intel made a huge mess out of his drivers for Linux from Kernel versions starting with 5.10 and up to now from my perspective.

    I just consoled into my TrueNAS, the kernel is "5.10.109+truenas" so considerably older than Unraid's kernel.

    Ah wait, TrueNAS is based on BSD or am I wrong?

    I don't think its coincidence.  I've got a 10th Gen i7 with the EXACT same issue.  If I blacklist the i915 module from loading my system is perfectly stable.  But as soon as I allow i915 to load, even if nobody is actively streaming or transcoding, after anywhere from a few days to almost a month, it will eventually crash without a hint of what happened being written to the syslog.  This happens with either an HDMI monitor attached or a dummy.  I travel a lot and use my NAS for a lot of stuff including home security so these random crashes can be a huge inconvenience if I'm out of town.

    Please share your Diagnostics.

     

    I really can't imagine why it is working fine on my system i5-10600 and on the system from @alturismo i9-10850K just fine (I'm using Emby/Jellyfin and he uses Plex/Emby) wher it isn't on yours, don't know if @sonic6 transcodes that much but he also is running a i3-10400 and it works there too with Plex from what I know.

     

    I think a lot of users are runing 10th Gen hardware transcoding without any issues so far also on the latest RC versions.

    I'll be running both systems in parallel for a while.  Assuming Quicksync hardware transcoding works and remains stable, I think TrueNAS will be an okay alternative for me.

    But what is different on TrueNAS than on Unraid? What Kernel version does your TrueNAS box run?

    I can also imagine that it has something to do that TrueNAS runs Kubernetes instead of Docker/Containerd/Runc

    Tautulli shows a transcoding action within 4 minutes to the last available syslog entry before my hard reset. Also the user was only able to watch 2% of the show, so I guess that was when the crash happened.

    Please first try if this was just a false positive and let the server run for a few days, maybe also try to power off the server, pull the power cord from the wall, press a few times the on/off and reset button (to completely empty the caps) and then turn it on again.

    I see, thank you for the information. If I can provide any additional information just tell me.

    Fell free to get back to me if the server crashes again and we can diagnose furter... I really hope this was just a false positive and that your server runns without a hitch now.

    Now I installed rc7 without any changes to my system and it crashed after only 1 day, also without any log entry again.

    Do you run the syslogserver on your machine?

    That's why I instantly thought the issues are back.

    Where you transcoding something with your iGPU bevore it crashed?

    No I'm not sure, I'm sure that my GPU was the issue in the past up till the hdmi dummy.

    Only a fix for Ice Lake CPUs was added but nothing that should affect your Skylake CPU.

    Upgraded to RC5 but none of my Plex containers would start. After a bit of troubleshooting it seems it wouldn't download the nvidia drivers and since I used that for transcoding the containers wouldn't start.

    Please create a dedicated post on the Nvidia Driver plugin support thread.

    I'm beginning to think I should stick a NVIDIA card in this thing and abandon Intel hardware transcoding.

    I'm having no issues whatsover with HW transcoding on my 10th gen Intel i5-10600 (having a HDMI 1080p dummy plug plugged in my iGPU), I also find the transcoding quality from Intel a bit better than NVENC but that is always subjective to the user... :)

     

    It's really suspicious to me that you have had issues on 6.8.2 too and also of course on newer versions.

    I ran it with a small monitor attached.  I've since switched to headless, but I haven't tried re-enabling QS in Plex/Handbrake.

    What CPU do you have?

     

    I‘ve know a few people that had issues when no monitor or HDMI Dummy device is plugged in to the iGPU and they try to transcode, issues like that the Kernel module for the iGPU generetad a Kernel panic, server crashes,…

    So I ended up ordering 10 different sticks yesterday in the hope that one of them has a usable UUID.

    I would recommend that you use a Transcend 32GB USB 2.0, you can get them over here in Europe pretty easily and they have a valid UUID.

     

    Never had a single issue with this devices.

    Mar 11 00:38:56 Jarvis kernel: [drm:__uc_sanitize [i915]] *ERROR* Failed to reset GuC, ret = -110

    Can you try to add: 

    i915.enable_guc=0

    to your syslinux.conf and test if it crashes again, if yes please edit this entry and try: 

    i915.enable_guc=2

    and report back if it's the same.

    Were hangs every week on i5-8600 last 3 months. Only hard reset helped a lot. But my server is remote machine so each hang is headache.

    Yep, can confirm 9th gen, i3 9100. No go with all 6.9.x and 6.10-RC

    i5-7600k

    Have you guys connected a Monitor or a HDMI Dummy plug to your iGPU?

    It is much recommended to at least attach a HDMI Dummy plug to avoid Kernel Panics with newer Kernels.

    I have /boot/config/modprobe.d/i915.conf with content blacklist i915 and Intel GPU Top Installed.

    In go file I have just 

    chmod -R 777 /dev/dri 

    Seems I am not using i915.force_probe=4680 or just to stupid to find it.

    Please don't do this, Intel-GPU-TOP will handle the force probe, just blacklist the i915 module, you even don't need to do a chmod -R 777 /dev/dri because Unraid does this itself if the path is found.
