Summary: DWL-650+ stop_net fails to unregister_netdevice()

Initial Comment:
I am using version 0.1h of the acx100 driver. I haven't
been successful to make the driver work with WEP.
However, the card did work in WEP-less APs. When I
execute the stop_net script (specifically, invoking #
rmmod acx100), the console hangs. I can't switch
virtual consoles (to/from XFree's vc/7). The console
printed the following output:

unregister_netdevice: waiting for wlan0 to become free.
Usage count = 2

The message kept getting printed. I suppose there's a
loop timed about 12 seconds. I think it is triggered
from lines in acx100.c, i.e., the line
unregister_netdev(netdev) in function
acx100_remove_pci() (I assume cleanup_module() is used
for 2.5.22 and up... and I'm using 2.4.22, so that
rules it out).

Gentoo Linux 1.4

Kernel: 2.4.22_pre2

GLibC:  2.3.2

GCC:    3.2.3

PCMCIA-CS: 3.2.4
acx100 driver: 0.1h

I've already submitted the hardware info into the
matrix, but I decided to repost it here for convenience.

Hi! The same happend to me using the kernel 2.4.22 in SuSE 8.2. After 
using the stop_net script I get the failed to unregister netdevice with 
*all* drivers. 

It never happens with the 2.4.20 Kernel. Everything works fine there... 

Strange....

The new version 0.2.0pre2 contains a fix for
unregister_netdevice() which *might* eventually fix it.
Please report back if it is working now.
