Only theory I can think of is that some device driver shuts off all interrupts and then goes into an infinite loop. I have had trouble with at least four different device drivers locking everything out long enough to lose incoming data. Usually it recovers without a reboot. Not an infinte loop, just way way too long to leave interrupts shut off. See also the "How to diagnose system freezes?" thread from July-August. Yuri found that a particular rev of the nvidia driver went into an infinite loop. _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
