Considering that you are running desktop hardware, I am not exactly surprised. But what makes me wo= rry is that in all cases exception happened while system was executing virtual machine, so it may be either a trigger (and I don't know much about AMD MCA= ) or just unrelated witness, just because this system spends most of its CPU time running VMs.=20 You may try to report this issue to FreeBSD in case somebody really knows h= ow to decode AMD MCA. But what I see now looks like checksum error in CPU L1 cache, which is a hardware problem. --=20 You are receiving this mail because: You are the assignee for the bug.=
