Does anyone know anything about Kernel 2.2's ability to watch for thread deadlocks, and kill off the offending thread? I remember reading a snipit somewhere that talked of this ability and problems people had been seeing. I have been looking through linux source for the code but have yet to find it. While constructing and formatting a massive raid 5 array on four 25gig IDE drives, I saw init run multiple times, and mke2fs was killed periodically with a signal 9 from nowhere. I assume that it is this watchdog code and I want to experiment with it. Clay
