Then suddently 2 days ago (didn't update the kernel or anything else), my PC started randomly rebooting when under load. Reading on problems with AMD cpus (and specifically 7950x), I bought a PSU and swapped it. Same problem. Then the cpu (for a 7600), then the motherboard, then the memory... same. I could 100% reproduce the problem by putting the VM under load within 3 minutes. AFAIK, there was no MCE logged. I finally stumbled on this thread, set kvm_amd.vls=0, and that indeed fully fixed the problem. I don't know how or why hyper-v was suddently enabled in my Windows VM, but that's obviously what happened. When it did, it triggered this bug quite violently. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
