Proxmox VE 9.2.21
After upgrading to kernel 7.0.14-20-pve I get a reproducible crash when starting a VM. This seems to be caused by a passed through em28xx-usb-tuner.
The VM will fail to start and the host is also not fine after that, e.g. it will hang on the 'rebooting now' and needs to be power cycled.
The crash only appeared with 7.0.14-20-pve, with 7.0.14-19-pve everything is good.
I guess the error would also happen if I just unplug the USB-device, but I haven't tested that.
