MCP5x seem to be infinite source of surprises. Some reports I remember: - snd_hda not working with MSI enabled - AFAIR not just loosing interrupts but completely stops responding; - using regular HPET interrupts breaks HDA sound after some time (interrupts are not shared), while legacy_route mode operates properly; - at least on one system I've seen non-functioning SATA interrupts. It would be nice to find what's going on there. I've got tired to add workarounds for it. :( -- Alexander Motin
