Not sure if KVM is the culprit, but it is the last line shown on the

Have you tried rmmoding the kvm modules before reboot?

Were any guests running during this?

hmm.... seems to be a side effect of https://lkml.org/lkml/2012/8/3/370.

Is it fixed with the patches for that?  We're operating on a NULL
pointer with that bug on your system, so you probably don't want to be
assuming the system is entirely healthy after you hit it.  Thanks,


Agreed and yes.

Latest Linus tree has the iommu patch. Still need to get the other one in (https://lkml.org/lkml/2012/8/4/141) or whatever alternative is deemed better.
