I've recently upgraded to proxmox 7 and started noticing my windows based VM's "Stalling" where it looks like if they have a GPU passed through the GPU usage skyrockets to 100% (even though the VM is doing nothing except having task manager open)
I quickly did a 'dmesg' and looked at what was going on, and everytime this happened i was getting the same line showing up.
This never happened in proxmox 6 and only happens with windows vm's... works totally fine with the same GPU passed through to linux machines.
the IO usage of the overall system is very low too.
What could be the reason why an interrupt it taking too long?
