FreeBSD 6.3 xl0: watchdog timeout

[Михаил Шпацерман]

Hi

I have a problen with FreeBSD 6.3. When I boot, I get the message
  xl0: watchdog timeout
and I have no networking. I have 3com ethernet card.

If i make ping on localhost it works good. But if i try to ping anything
else it didn't work. When I plug the 3com ethernet card into other
systemblock with FreeBSD 6.2, and activeted it. All worked good.

Help to solve this problem. Maby it is problem with BIOS?
