Hi, Thimo,

I cannot reproduce this issue in my box after running about two weeks:
I started four guests (two PV guests and two HVM guests). And each guest runs a 
simple workload (ping a remote machine). After two weeks, the machine still 
works no crash and panic happen. Are there any special workload required to 
reproduce this issue?

Attached the cpuinfo and pci info in my box. Please compare it with yours to 
see whether it is same. Especially, the microcode version.

Best regards,
Yang
