Hi Dominik.

Thanks for the patch !

The devices have been assigned the missing IRQs. The network card keeps
having some problems, but I believe is now a driver related issue.

This is what I get when activating the network card.I'm copying this
message to Donald Becker, the developer for the tulip driver.

Apr 3 12:28:47 inferno kernel: NETDEV WATCHDOG: eth0: transmit timed
out
Apr 3 12:28:47 inferno kernel: eth0: Transmit timed out, status
fc674055, CSR12 00000000, resetting...

I'm attaching the latest dmesg and lspci so you can take a look at it
and check for possible hot-spots.

Thanks again for your help.

Regards,
Luis
