NIC, unable to handle kernel NULL pointer dereference


Hi all,

I'm running Debian (kernel 2.4.18-bf2.4); ive been trying to get the builtin NIC on my asus a7v600 to work. i d/led the 3c2000 driver and tried to compile. after a few hours of messing around with the driver files, trying to get them to work, i popped in an older NIC i had lying around, linksys lne100tx. i added the 'tulip' module like some online posts suggested. this time, when i connected the network cable, the LEDs in the back came on! yay. i thought i was home free, but when i typed ifconfig, i get the following msg:

unable to handle kernel NULL pointer dereference at virtual address 00000001

printing eip:
00000001
*pde = 00000000
Oops: 0000
CPU: 0
EIP: 0010:[<0000001>] Not tainted
EFLAGS: 00010202
eax: 00000001 ebx: c1855c00 ecx: ffffffd edx: 00000143
esi: db8dd143 edi: 00000400 ebp: 0000000 esp: dbbdff3c
Process ifconfig (pid: 267, stackpage = dbbdf000)

Stack:

Call Trace:

Code: Bad EIP value
Segmentation fault

i THINK it may have something to do w/ having two network cards installed at once, but when i rmmod 3c2000 (the builtin NIC) it says that it isnt installed to begin with.

any suggestions??

Thanks in advance.

i figured out what happened. i unplugged the PCI NIC and it still gave me the same error-- i think it was caused by my messin around w/ the 3c2000.o driver... in any case, i reinstalled the OS and it works now*

*i can ssh into my box from the LAN, but the box doesnt seem to be able to access the internet. any reason why??

thanks
