           Summary: divide error: 0000 [#1] with VIA Velocity when unplugged
           Product: Other
           Version: 2.5
     KernelVersion: 2.6.22.12 (openSUSE 10.3)
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1

Most recent kernel where this bug did not occur: I've never seen it before.
Distribution: openSUSE 10.3
Hardware Environment: AMD Athlon 2200+
Software Environment: openSUSE 10.3
Problem Description: I unplugged my VIA Velocity and plugged it back into a switch and shortly thereafter it gacked.

I ran 'ip -s -s link show dev eth1' which sigsegd (this machine has been rock solid for YEARS so I know it's not the hardware) and the machine locked up. The blinkenlights on the switch continued to blink but according to tcpdump no traffic was flowing from this machine. A reboot later confirmed a problem and I found this in the /var/log/messages file:
