Description of problem:
Hi, I don't think this to be a bug in this specific application, but
it occures while starting it. The problem could also have something to
do with the kernel. So, step by step:

After I compiled and installed the cvs-snapshot of the
at76c503a-driver (at76c503a.berlios.de) I plugged in my "T-Com T-Sinus
130 data" (a WLAN-device based uppon the "Siemens Gigaset USB card
11") that I'm used to use under Windows. The driver started correctly
and the device was registered as "wlan0" (according to syslog). But if
I now try to start the system-config-network-application to configure
the device the whole system hangs. The only way to get the system
running again is to restart the computer by pushing the power-button
for 4 seconds. Then one should plug out the device, because there's a
fatal kernel error while booting.

As I tried other applications that need to search for the wlan-device
(like the hardware explorer/manager (translated from german)) the
error also occures.

I don't think that this has something to do with the driver itself,
because it is also used for the upcomming Suse Linux 9.1 release, but
I'm a Linux-beginner, so I'm perhaps unable to judge about this.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. compile and install the at76c503a-driver
2. plug in the device
3. try to start the application

Actual Results:  system hang

Expected Results:  the application should start normally

Comment 1 Harald Hoyer 2004-04-14 09:27:15 UTC
system-config-network uses iwconfig to configure the device... so if
this driver does not support iwconfig or crashes the system, it is the
drivers fault...
