Thanks for your reply - keen as ever to get this sorted out.  Apologies 
I didn't get back to you yesterday - insane day :-(

Note, this is without DEBUG enabled; I'll recompile my kernel in a 
minute and post results with it enabled.

The particular card I am trying is a Senao 200mW 16-bit PCMCIA card, 
more information at:


It's not just this card, though; it happens with other cards I have, too 
(i.e. 16-bit Orinoco card).  I believe one card is 3.3V, and the other 
is 5V, but I can't recall which is which.

Also note that the same cards, with the same cardbus controller, with 
the same hard drive (i.e. userland/configuration/tools) work flawlessly 
on a different motherboard.

Yes, it works on another board.  No, it does not work on the same board 
with Knoppix.

Ok, I'll toy with this; not sure exactly what I should set them to, though.

Me too, thanks for your help :-)
