- Urgent
After I updated from rc2 to rc3, the server crashes on me usually within half an hour after booting. The system freezes, web UI unresponsive, sometimes I manage to log in via SSH but in the end I have to hard-reset the server (more specifically, I have to power off the server with a long press and then start again – pressing reset or short-pressing power button does nothing, as does running "reboot" in SSH console).
Because of the crash causing web UI to stop responding, I was unable to get diagnostics at that moment – the attached diagnostics are right after a boot with rc3 (before the crash). One time I managed to be logged in via SSH when it crashed and got the "dmesg" output (attached). Seems to be related to "i915" and the symptoms in general seem to be similar to this old issue.
I did the upgrade in the middle of the night, so even though I have a few Docker containers set to autostart, nobody was really using the server (= no transcoding in Plex etc.), it was just idling and still crashed nevertheless.
I did change some BIOS settings (enabled some power optimizations and set fan curves) before booting into rc3 but now that I reverted back to rc2 everything seems to run fine with the same BIOS setup (running for 20h without a crash now), so I don't think my BIOS changes play a role in this issue.
Please let me know if you need me to run some more tests.
