Hello,

I'm experiencing strange behaviour with any FreeBSD 64bit running under KVM
Qemu. When machine is under high load for example compiling from ports,
after a random time it will get rebooted with no piece of information in
logs or what so ever. In this case I'm unable to get any kernel
panic/traces (kdb is enabled). On the KVM side also there are no error
logs.

This is confirmed on FreeBSD amd64 8.4; 9.0; 9.1; 9.2-RC and 10-Current.

Anyone experienced such behaviour on 64bits or mayby have a clue how can I
debug this?

With kind regards,
Matthew
