Getting a few watchdog timeouts is not unexpected in this case, since
it means you lost an interrupt somewhere, which I suppose can happen
if the host CPU is slow or very heavily loaded (which I guess it
would be if you're building world). Hopefully it recovers quickly.

FYI, this is a bogus station address. There are two bits in an
ethernet address that have special meaning. If bit 0 in the first
octet is set, then the address is a multicast group address rather
than a unicast address. (Hence ff:ff:ff:ff:ff:ff is technically a
special case of multicast.) If bit 1 in the first octet is set,
the address is locally defined rather than globally assigned.

Bit 1 is set in your address (the 2 in '52') which means either the
code to read the station address from the NIC is broken, or the
EEPROM on your card is scrambled. Or both.

Another dead giveaway that the address is bogus is that 52:54:4c is
not registered in the IEEE's OUI database:
