Crash with 3c59x.o

[Hans-Joachim Baader <hjb@pro-linux.de>]

Hi!

I experienced a reproducible crash with the 3c59x network module on my dual
Celeron machine. To reproduce, do the following:

/etc/init.d/networking stop
rmmod 3c59x; modprobe 3c59x (several times)
rmmod 3c59x
/etc/init.d/networking start

Then the system freezes. All kernels from 2.4.20-rc1 to 2.4.21-pre2 appear
to have this bug. Some time after the freeze, a message appears, I didn't
copy it completely:

wait_on_irq, CPU1:
irq: 1 [ 2 0 ]
bh:  0 [ 1 0 ]

CPU 0 call stack appears to be empty
CPU 1 call stack appears to be:
  __global_cli flush_to_ldisc __run_task_queue context_thread kernel_thread

As you can see, there are two 3Com cards which are both recognized by the
driver.
