[SOLVED] Passthrough USB device causes proxmox problems, time out waiting on systemd

[gouthamravee]

Proxmox Version: 7.1-11
Kernel: Linux 5.13.19-6-pve #1 SMP PVE 5.13.19-14
CPU: AMD Ryzen 3 2200G

I have a virtual machine for Plex, I want to pass through a USB TV tuner to the VM.
I'm doing this by adding the USB device in the hardware section, using the USB Ven/Dev ID.

When I attach the device and restart the VM the whole node becomes unresponsive.
Trying to start the Plex VM gives me this error in the GUI - time out waiting on systemd

There's one other VM on this node, and in this state I can't stop that node.
The USB device doesn't show up on the hardware list anymore, I can't add or remove it.

Only option is to force a restart of the whole node using the power button.

Any idea what could be going on here?

This was working before on Proxmox 7.x, I'm not sure when it stopped working though.

Reverting to a previous kernel, in this case 5.11.x fixed it. Seems like a bug in the 5.13 kernel.

make sure to read carefully and double check everything before rebooting.
