Description Robert Maerzke 2009-12-18 06:20:01 UTC

After upgrade from 7.2 to 8 my 3c509b NIC cards will not work.  I can
ping the IP address of the card from within the machine.  However, I
can't access anything external.  If I run TcpDump, the card will start working.

Fix: 

Running tcpdump from the console restores network connectivity.
How-To-Repeat: Reboot after upgrade to FBSD 8.0

Here's the relevant lines from dmesg:

pnpid TCM5094 on isa0
ep0: WARNING: using obsoleted if_watchdog interface

I'm seeing this same problem now that I installed FreeBSD 8.2 on my =
laptop.  Sometimes it will lock up even from just doing "ifconfig -a".  =
I can get it to come back if I do "ifconfig ep0 up" a few times after =
waiting a while.  I'm guessing it has to do with the "ep0: WARNING: =
using obsoleted if_watchdog interface" upon startup.
