I was thinking more of a driver change that is being triggered on that particular hardware. FWIW, did you test 2.6.19? I really need a better idea of the workload these servers are running and, ideally, a reproducable test case to track something like this down. At the moment I have no idea what is going on and no real information on which to even base a guess. Were there any other messages in the log?

If it does fix the problem, then I'd be pointing once again at hardware ;) Cheers, Dave. -- Dave Chinner Principal Engineer SGI Australian Software Group - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
