I am currently running 2.4.18-pre9-mjc2, but this also happens w/ 
2.4.18-pre9 (and 2.4.18-pre7-mjc, maybe others)

I am getting NETDEV Watchdog timeouts

I have been getting this at largely unpredictable intervals. The 
solutions seems to be to ifdown the ethdevs, and rmmod the driver. then 
ifup the ethdevs (which also means I have to stop my PPPoE-DSL 
connection).

eth1, the dev that is timing out is not sharing its interrupt.
These boards are/were marketed under the brand name SVEC. I cannot find 
the box they came in at the moment, so don't have the model number.

Just for reference, here's the relevant lines from lspci -vv
