All seems to be working fine, still ;) just to make sure the original point gets across: the warning is only in the -rt tree, and it pinpoints potential SMP bugs. Does your box do hyperthreading? If yes then this could be a live (but probably mostly harmless) SMP bug. Maybe the whole IRQ disabling is unnecessary? __devinit is mostly serialized, so i'm not sure there's any protection needed against parallel IRQs?
