Re: network problem: me or problem with tulip/unaligned trap?
I would try different milo/kernel combinations. I found the milo's from
the DEC site worked better for me. I've got a AlphaStation 200 with a
DEC NIC and the tulip driver works perfectly. I've also got a DEC chip
NIC on intel Linux and the tulip driver works fine there too.
For more info on tulip:

If you do get around to recompiling the kernel, make sure you make a new
milo.
Also, for the future, if your card is autosensing you have to pass it
options so it knows what mode to be in (i.e. 100TX), etc.
