I've built the module against the Debian "official" kernel
2.6.14-2-686 (version 2.6.14-7).
I have a ThinkPad A22p and an Enterasys Networks PCMCIA a/b/g card. I
will attach the output of "lspci -vvv".
When I click "scan for networks" in kwifimanager, kwifimanager
crashes, and dmesg shows this:
How about when using the wireless tools from commandline for scanning?
Does this also cause instability?

It may be related to the inability of this module to do background
scanning, or it could just be a plain old bug in the code. Try using the
basic wireless-tools and refrain from using the graphical apps, and see
if you can reproduce this instability.
This version of the driver is the most stable offering from the madwifi
project however it is still tagged as beta code, so it is known to cause
instability on some hardware.
Thanks, Kel.
