Actually judging by the INT disabled message that appears after the 
WARN_ON - 

0000:01:00.0: PCI INT A disabled

It seems to be the PCI bridge that was in D0 - 
00:01.0 PCI bridge: Intel Corporation Mobile PM965/GM965/GL960 PCI Express 
Root Port (rev 0c)

(Or did you mean patch to fix the WARN_ON is on the way - that would be 
even better :)

Sure :) I will let you know shortly, the desktop machine is compiling 
right now, once that's done...
