Hi! I've had a Coral TPU passed through to an Ubuntu 22.04 LTS VM for a while, and as far as I know it's been working well. However, I recemtly noticed that the Frigate docker container was crashing every few seconds. On further investigation, it's reporting that it can't find the Coral TPU. In the VM, the TPU is there, but there are no apex_0 or apex_1 devices:

Code:
lspci -nn | grep 089a
06:10.0 System peripheral [0880]: Global Unichip Corp. Coral Edge TPU [1ac1:089a]
06:11.0 System peripheral [0880]: Global Unichip Corp. Coral Edge TPU [1ac1:089a]

ls /dev/apex_0
ls: cannot access '/dev/apex_0': No such file or directory

I've tried reinstalling the drivers in the VM, but to no avail. I noticed there were a few threads on here talking about problems with gasket since a recent update of Proxmox, Not sure if there's a known issue? Please can anyone help me figure out what the problem may be?

Thanks!
