Subject: kernel BUG at arch/x86/kvm/mmu.c:655!
Date: Fri, 07 Jan 2011 21:43:57 +0100 [thread overview]
Message-ID: <4D277B0D.8070505@wpkg.org> (raw)
The following happened when I tried to reboot a virtual machine (host running qemu 0.13.0, kernel 2.6.36.2).
After a while, the server hanged and was no longer reachable.
