[Xen-devel] hypervisor crash when shutting down domU in tonight's -unstable

["Christopher S. Aker" <caker@xxxxxxxxxxxx>]

Latest -unstable, issuing xm shutdown results in the following crash.  I have a
suspicion it'ss related to "ChangeSet 1.1340.1.1":

> Patch to enable the destruction of domains which have shadow mode enabled.
> Also fixes some shadow mode ref counting bugs, and one bug in check_pte()
> recently introduced by the changes in page table accessor types/macros.

Fake shadow is off in my dom0 config.
