Yes, I'm doing PCI passthrough (the IGD, audio && USB controller). But this is actually a PVHVM guest since debian stock kernel has PVOP enabled. And when I tried another PVOP disabled linux distro (openelec v2.0), I did not see such msi related error message. Actually, with that domU I do not see anything obvious wrong from the log, but I also see nothing from panel (panel receive no signal and go power-saving) :-( Back to the issue I was reporting, the domU log looks like this: Dec 2 21:52:44 debvm kernel: [ 1085.604071] [drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... blt ring idle [waiting on 3354, at 3354], missed IRQ?
