Public bug reported:
The pt3_drv driver, which worked fine with kernel 6.8.0-40, stopped
working after updating to kernel 6.8.0-45.
The same driver works fine with proxmox-kernel-6.8.12-1-pve-signed on

The driver is the one on github below.

The AMGPU patch captured in 5.14.0-1007 was added to uvd_v6_0_hw_fini.

location may be wrong.

If you replace driver / gpu / drm / amd / with the source of
5.14.0-1005, it can be unloaded normally.
