Ok, I think I found the problem
Xircom PCMCIA Ethernet Adapter Issues
Kernel oops when ejecting CBEM56G (Eyvind Bernhardsen)

Try today's beta (09-Feb-00) on sourceforge.org in /pub/pcmcia/NEW.
I think the problem only shows up on 2.2.14 kernels, thanks to a
kernel change meant to catch memory allocation errors.
