Presumably some access that the CPU is doing to the controller has timed out and caused the MCE. It might be useful if we could get a stack trace from where the MCE was triggered - does anyone know if it's possible to do this? It's possible that only NVidia really could tell why this error would result from a disk problem, though. -- Robert Hancock Saskatoon, SK, Canada To email, remove "nospam" from hancockr@nospamshaw.ca Home Page: http://www.roberthancock.com/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
