So far so good! I can normally trigger it within 20 minutes and today

I think I found the crash and got it fixed. If you can confirm this
fixes it for you, I'll get it uploaded to the main archive. Thanks for
doing all the gdb debugging!

Yup, that turned out great. I'll continue digging. Thanks!

Kees, I appreciate all your help and I will get you that backtrace when
I get back home tomorrow. It very well could be the driver itself a

Well, I spent some time digging around in
wpa_driver_wext_get_scan_results, and while it's scary to read, the
overflow isn't obvious yet. Can you try another gdb recipe? This one
is quite a bit more exciting -- it tries to break out the moment the
stack gets trashed. Here are the commands, after

Hi, if you can reproduce this issue, can you start up everything, but
before the "stack smashing" would normally happen, try this:
$ sudo gdb /sbin/wpa_supplicant $(pidof wpa_supplicant)
...
(gdb) br __stack_chk_fail
(gdb) continue
Then once gdb pops at the stack check failure, do:

Alexander, I did as of last night with a system that was completely up

As a note I did not see the problem with Network Manager stopped and
