i have a DEC DE450 (based on 21041 AA chipset). i guess, for
2104[01], tulip driver has been broken since 2.4.4 (yes, that's over
six months of brokeness). yes, jeff garzik knows about it. i've
emailed the list and sourceforge &c.

rememdies --

0) buy a new network card.

1) use the de4x5 driver instead.

2) use the older tulip driver 0.9.14. download it from

if you go with 2, just download. have /usr/src/linux be your linux
source (or a symlink to them). go into tulip-0.9.14/src, make dep,
make. then copy tulip.o into /lib/modules/2.[45].X/kernel/drivers/net/tulip
which replaces the kernels one.

best of luck.
