I have 2: 1.) Bad NIC 2.) Bad CPU A while back, I found out I had a bad CPU after replacing everything else on the machine -- I would still receive CRC mismatch errors with portsnap(8). The NIC is more probable IMHO, but both should be suspect here. -- Glen Barber _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
