Hi,

I have problems getting my smc 1255 card to work on my intel linux box. The
tulip driver recognizes my card as Accton EN1217/EN2242, and everything
seems to be ok until it receives an nfs mount request. The nfs mounting
works, but shortly afterwards, the network becomes extremely slow. I want to
debug the problem, but I don't know how to. I'm currently using kernel
2.4.18, and the included tulip driver, but I've also tried some older
versions.

/var/log/messages shows the following messages from kernel:

I've run tulip-diag after the network went slow:
