If I remember correctly, there were two problems: 1) there was a race in the interrupt handler (this affected all interrupt handlers), 2) em used the now obsolete if_timer to implement it's watchdog timeout. This timer is unreliable. Both items have been fixed, so this shouldn't be related to your problem. #2 wasn't fixed in all drivers, but if you are affected you should see a warning on startup stating the use of the obsolete timer. I believe if_re was converted some time ago. Note that in theory watchdog timeouts could also mean broken hardware, bad connection to PCI bus or other intermittent hw failure. I would try reseating the card in another slot. -- Pieter de Goeje _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
