*sigh* I don't have any cardbus cards that reference external firmware.

I can't begin to tell you where the problem is, since a) you only
gave me one instruction where the crash occured, rather than showing me
the entire stack trace and console display so I could see what other
messages (if any) appeared on the console when it happened, b) you
didn't tell me what speed/mode you were using at the time, and c)
you have not provided a more precise means of duplicating the crash
(I can't do cvsup from home: I only have a dialup). Cvsup is not
a network diagnostic or traffic generation tool: it is not possible
to generate consistent, reproducible results with it. Use ttcp or
netperf instead, then show me _EXACTLY_ how you ran it to produce
the crash so I can do it too.

I don't have a card like this. What chipset is it?

Grrrr. For the Nth time: this is a PCMCIA card, not cardbus. I already
said I haven't added support for PCMCIA cards yet.

"Halts" == freezes up? Or do you mean it resets?

What chipset is this card?
