snailtrails Posted January 19, 2022 Share Posted January 19, 2022 Not sure why my unraid server is becoming unresponsive after some time (a day, sometimes few days). All new parts. I attached zip file but this was after reboot. Not sure how I can generate log file before it becomes unresponsive. i5-11600k (stock clocks) XMP RAM profile 3200mhz Using igpu Usb 2.0 flash drive z590 motherboard gigabyte Unraid version: 6.9.2 ur1-diagnostics-20220119-0822.zip Quote Link to comment

snailtrails Posted January 20, 2022 Author Share Posted January 20, 2022 (edited) Sounds about right, buggy linux intel IGPU drivers + plex hardware transcoding. I don't really want to give up HW transcoding with Plex. I guess wait until a new linux gpu driver? Could be unraid related maybe but sounds more like linux intel GPU buggy drivers. Also probably doesn't help I am 11th gen intel which isn't officially support by unraid yet either. Do you know how to turn on some type of logging so I can try to produce an error report before it becomes unresponsive? Edited January 20, 2022 by snailtrails Quote Link to comment

According to the bug report it just crashes without spitting anything to the log. Quote Link to comment
doobyns Posted January 20, 2022 Share Posted January 20, 2022 do you use plex ? if yes the latest versions are plagued by bugs, stick to version 1.24.2.4973, it's one of the last without the bug. Quote Link to comment

snailtrails Posted January 25, 2022 Author Share Posted January 25, 2022 Server has been running fine for a 5 days now without issue now that I disabled HW transcoding on plex for now. Still not sure if igpu driver or plex related. Quote Link to comment
akawoz Posted February 6, 2022 Share Posted February 6, 2022 I'm been doing a bunch of testing after replacing my Xeon E5-2696v2 + GPU and Supermicro motherboard setup with a Z590 + i5-11400 combo using Quicksync and have arrived at a stable solution that allows me to hardware transcode with the latest Plex builds. I have issues with any Unraid release from 6.10.0-RC1 including RC2 and the latest test builds beyond that. Regardless of my setup including blacklisting i915 in favour of GPU Top I still have crashes when Plex uses hardware transcoding (incl current build 1.25.5.5492). My server will hang (no video, keyboard, mouse) and drop from the network. Requires hard reset. My solution: Unraid: 6.9.2 Plex 1.25.5.5492 config/modprobe.d/i915.conf = options i915 force_probe=4c8b no GPU top or GPU statistics installed My force_probe=4c8b because when I tried 4c8a I got a message in dmesg that told me to use 4c8b instead. My CPU config is below for reference. Hope this helps someone - this was very frustrating going from an incredibly stable Xeon build to an i5-11400 and having unpredictable crashes without anything in the logs. Cheers!

Once I started doing some hardware transcoding the server once again locked up after about 15 minutes. Quote Link to comment
