I am still struggeling with PCMCIA ethernet cards. However the story has 
changed from an unsupported piece of hardware to a supported piece of hardware 
that doesn't work.

I have one PCMCIA NE2000 compatible network card that is not recognised by the 
NE2000 PCMCIA detection code. I added the recognition strings into the 
appropriate table in if_ne_pcmcia.c. After which the card was detected and 
attached as ne2. But when I tried a simple ifconfig ne2 192.168.0.4 the 
machine frooze. (not even keyboard input is echoed anymore) (BTW: if I do 
ifconfig ne2 up, the keyboard is echoed but ^C does not present a prompt, I 
try to retype what I see in the debugger below)

I got some other cards on loan. One of which is recognised by the 
generic 1.3 kernel! The device attaches but I still get the freeze.

This smels like a bug.
The machine is a Pentium 200 MMX

this is the dmesg output:

The card that I inserted is a combo card. When I do ifconfig ne2 the result is

	media: manual (none)
	inet 0.0.0.0 netmask 0x0

I try to investigate further. I have already established that the code is not 
in ne2000.c when the freeze occurs.

Any help would be appreciated.

I don't know how to interpret this output. Could someone educate me?
