I'm sure I encountered the same problem. It seems to be a problem with pve8.1, because I used pve8.0 (upgraded to pve8.1) and it was ok. I also used the 6.5.13-1-pve kernel. I hope anyone can find the problem. Please share the solution, thank you.

Good news, I have solved this problem. My problem occurred with secure boot. If yours is the same as mine, you can try to turn off secure boot or load the DKMS key. The general process is as follows: mokutil --import /var/lib/dkms/mok.pub (set a password) reboot \<Startup screen operation>: Enroll MOK, Continue, Yes, <password>, Reboot Hope it can help friends who encounter the same problem

i have the same problem. but this don't work for me. i don't enable secure boot.

chchia commented 7 months ago

for me it was secure boot. proxmox enabled secure boot by default now.

chilltrout commented 2 months ago

did anyone resolve this? I'm also secure boot turned off and can only see 00:02.0 after following the docs on 6.8.12-1. I do however have the whole device passed to my HAOS VM running frigate inside it and it sees the GPU and tries to do HW decoding but wont have a bar of my reolink cameras or openvino
