PVE crashing / hanging with very high load average

[usridzero]

Hello,
My PVE keeps crashing or hanging and not responding via GUI or ssh. After rebooting everything is okay for a while and then the load goes up until the system stops responding. I trace the issue to a KVM process taking all the CPU resources. Here are some journal logs:

you have a known problematic CPU, and the symptoms match the problems reported for it, I would consider sending it back to Intel/your supplier:
