Hi,

please post the output of pveversion -v. There have been several known issues with this CPU model [1], did you try out the suggestions from the other post [2]?

I have similar issue with OVS and kernel >= 5.15 you should try pve-kernel-5.13

Finally,I reinstall to pve 7.1with 5.1.3kernel,its been working stable for 3days now.
