MB: ASUS PRIME Z590-P (latest BIOS & cstate disabled)
RAM: PNY XLR8 EPIC RGB 32GB (2x16GB) DDR4 3200Mhz CL16

Sorry you did not get a reply to this. Are you using the intel iGPU for transcoding?

Thanks for notice!😇

Yes i do use Intel iGPU for transcode, but i didn't use plex at the time when it died.
I hasn't crash when id use Plex so far, Its so random. I only notice it because my phone cant sync to my Nextcloud.

I have now reset my BIOS and turned of XMP-profile (even tho memtest said it was all ok)

Is there any good software to test other hardware? I suspect hardware-failure tho the server has no time to write any errors to the syslog.
I also have problem shutting it down and stop the array. Problem with unmount, even with manual umount -f (target busy)

I think there may be an issue with the intel iGPU module causing the system to hang (even just being loaded). 6.8.3 fixes this for me but I am talking with the moderators about a solution that allows a more modern version of the OS.

Okay! Is there a way to see if thats the problem i have?

Any ways to trigger a crash och something to look for in the logs?

[Tristankin]

Absolutely nothing for me. It's the reason it has been generally blamed on hardware faults. For me it would happen within 2 days but generally at random. No load required.

If you don't have a lot of people transcoding you could try unloading the i915 module?

Yes i can try, i now(since yesterday) run the newest beta release of Plex that's finally able to transcode with the 11th gen cpu's quicksync.
Could it be Plex that's been causing the problem?

If its crash again, im gonna try to disable/unload the iGPU.

Btw: Whats the correct way to unload the iGPU?
#vi /boot/config/modprobe.d/blacklist.conf
options i915 force_probe=4c8a

That bit is a bit beyond my understanding....

But this I think steers you in the right direction: https://wiki.unraid.net/Manual/Release_Notes/Unraid_OS_6.9.0

just remove the /boot/config/modprobe.d/i915.conf file?

Thank!

I'll try next time it crashes.
