Subject[OOPS] net/8139too
Hello LKML!

Since linux-2.4.15-pre[14]+kdb+freeswan I get an oops when stopping my
8139too network:

# ifdown eth0
eth0: unable to signal thread
# rmmod -a
<<< Unplug the network kable >>>
Inable to handle kernel paging request at virtual address c904b600
printing eip:
c904b600
*pde = 0127d067
*pte = 00000000

Entering kdb (current=0xc792a000, pid 59) Oops: Oops

eax = 0xc904b600 ebx = 0xc217aaa0 ecx = 0xc9065000 edx = 0x00000020
