Upgraded my Proxmox VE environment, consisting of 7 HP Elitedesk/Prodesk mini servers, a few days ago.
Was running 8.x.x for ages without any issues, now has 9.0.10 (latest and greatest).
Since the upgrade one of the servers (HP Elitedesk 800 G4 mini 65W) started rebooting randomly, sometimes more than once an hour.
Updated the BIOS to latest version.
Server was running for a day without issues (with DisplayPort monitor and keyboard attached). So I thought the BIOS update fixed it and disconnected the monitor and keyboard (hey, it's a server not a desktop). And ... the system started rebooting again randomly.
Then I remembered an issue with i915 drivers causing kernel panics when no DP display is attached. See https://forum.proxmox.com/threads/p...ues-with-hardware-transcoding-in-plex.132187/
So, I added 'i915.enable_dc=0' to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub and executed "update-grub" + reboot.
Since that modification no reboots anymore.
Perhaps a regression with the i915 driver?
