Having looked at the commit the Arek's bisect turned up I don't think it's
likely to have caused this problem to appear.

It seems that the regression had been introduced before the PM and PCI updates
went it, so I bet it's one of the x86 changes.  Ingo, are there any commits
obviously worth testing?
