A machine at a customer's site (running kernel 2.4.21) has stopped
answering over Ethernet today. The machine itself was still there and
the customer could log in at the console. A reboot fixed the problem.
The machine has had these error messages in the syslog about once per
hour for about 24 hours:
Mar 9 16:17:38 mail2 kernel: tg3: eth0: transmit timed out, resetting
