Yes, I asked Greg about that - we don't know what's causing it yet. I have
a bad feeling that this bug will go into Linus's tree if we don't fix it
quick.
I had problems with gregkh-pci-x86-pci-domain-support-the-meat.patch. It
might be worth reverting that.

I'm not aware of any buggy x86_64 patches in -mm2 :(
I guess you don't have the time to sit down and do a bisection search.
It'd take a solid few hours...
