I am running Proxmox version 6.2-6 on my Intel NUC (https://www.intel.com/content/www/us/en/products/boards-kits/nuc/kits/nuc8i3beh.html). One of my virtual machines is running home assistant for home automation (https://www.home-assistant.io/). I use a specific usb stick (https://phoscon.de/en/conbee2) that is plugged in into the NUC and I configured it under the USB device section of the VM:

Now this setup seems to be working for +- 5 days, but then suddenly the whole system freezes and I need to manually reboot the NUC. Because this has happened a couple of times and my NUC is headless I decided to add an old monitor so I could check the error once it happened, here is the result (sorry for the monitor quality, it's really old):

As you can see I am experiencing a kernel freeze but I am really not sure what is causing this, I found a similar post @ https://forum.proxmox.com/threads/usb-redirect-not-working-intermittent.70789/ but it did not provide a final solution other than updating which I did and I still got the error right after my first reboot. Any help is appreciated!

What is current version of your kernel? could you post output of pveversion -v?

@matrix this might be a stupid question, but do I apply those values on the pve node or on my vm instances?

I updated it on the host, hopefully I was right :D lets see what happens the next 2 weeks.
