kernel: NETDEV WATCHDOG: eth0: transmit timed out

[Sven Dowideit]

I have an IBM thinkpad T21 that has a 3Com ethernet card that has not
been working in a long while (with ACPI turned on).

Recently (the last 2-3 releases or so) it has also been getting the
following messages (until i remember to to an ifconfgi eth0 down)

Feb 23 00:22:00 sven kernel: NETDEV WATCHDOG: eth0: transmit timed out
Feb 23 00:22:35 sven last message repeated 3 times
Feb 23 00:23:35 sven last message repeated 5 times
Feb 23 00:24:35 sven last message repeated 5 times
Feb 23 00:25:35 sven last message repeated 5 times
Feb 23 00:26:00 sven last message repeated 2 times


the other weird thing, is that my computer pauses every few seconds, for
a second, and it seems like this symptom goes away after the ifconfig
down. 


any ideas?

cheers

Sven

Does it work with ACPI disabled?
