I've had this network bug for the entire to 2.3 dev to 2.4 final and now even 
in 2.4.4. Whenever I have high network traffic I get an ethernet transmit 
timeout error by netdev watchdog. This is with a ne2k-pci network card, and 
smp celeron machine. Reinstalling the module doesn't fix it, restarting dhpcd 
doesn't fix it. Reboot does. Kernel config attached.
