Alex,

Applied this patch on 3.8-rc3 and tested it. reboot still hung. The
only thing that fixes the problem is reverting
71e3d1578c954cf29f1f4db1c8930d3574025eb0

I am also seeing DMAR errors on this device starting 3.8-rc3 and I am
going to start bisecting that soon. Reverting
71e3d1578c954cf29f1f4db1c8930d3574025eb0 doesn't help solve the DMAR
errors.
