Issue: When a linux VM boots with my passed through 3080, I can no longer access the GPU after reboot. Requires server reboot to resolve.
Details:
-Can reboot with no issue with my Window’s VM.
-Appears to related to recent linux prop drivers. Had a out of date ubuntu VM that had the passthrough, no issue in that until I tried switching from nvidia 525 to 535.
-When rebooting a linux VM, the screens will briefly wake at boot, but no output.
Things tried:
-remove and rescan the pci device by echoing to the pci functions
-unbind and rebind vfio
-attach a virtual screen to see if it gets output, no success.
-looked through syslog, dmesg - nothing amiss.
Setup:
x570 dark hero w/ 5900x
tuf 3080 10G oc
proxmox 8.1.3 (kernel 6.5.11)
fully patched bios.
