Dell Precision 330 (Pentium 4, i850 chipset, 3c905c)

What is the output of 'lspci -v'? If it says that the chip revision is '78' then this is one of the new 3C905CX (note the CX) NIC's or ASIC on the motherboard. I've seen a problem with the 3c59x.c driver and this chip, it can send packets but not receive any. The 3Com 3c90x-1.0.0i.tgz driver at
http://support.3com.com/infodeli/tools/nic/linux.htm should work with this chip.

There has been some discussion of this NIC on the vortex mailing list at
http://www.scyld.com/network/vortex.html , with a patched driver to make for this chip available for testing at Andrew's web site
http://www.uow.edu.au/~andrewm/linux/#3c59x-bc (see the '2.2.19pre2 driver for testing').

Yes, it is rev 78, but I have at least 20 of these working on other machines (Precision 620) for a long time now. The difference in this machine is the i850 chipset vs. the i810 in the 620.

This seems to be a problem of 3c59x making a successful call of request_irq(), but nothing shows up in /proc/interrupts. It sounds like something is getting dropped on the floor somewhere else.

I will try the patched driver on Andrew's web site.
