crashed system

Description of problem:

hardware: thinkpad R61 model: 77381GG
fedora 10, gnome 2.24.3

Sometimes but reproducible I get a frozen system while I'm surfing with my firefox in the internet. Because it always happens using the wlan connection (and never happens using the lan connection) I think it is a networkmanager problem. But I'm also using always the firefox at the moment the system had crashed. This is the last event from the messages log before the system was frozen:

Mar  4 02:35:32 fedora NetworkManager: <info>  (wlan0): supplicant connection state:  completed -> group handshake
Mar  4 02:35:32 fedora NetworkManager: <info>  (wlan0): supplicant connection state:  group handshake -> completed

If the system crash the led for wlan and caps look are flashing (see video) and I can only reset the system because no magic keys are working.

Because it happens only sometimes and maybe after 1 hour using the wlan connection I need some instruction how to produce a useful trace etc.

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

networkmanager 0.7.0
firefox 3.0.6

How reproducible:


Steps to Reproduce:
1. wlan connection with wpa
2. using firefox
3. after a while the system crash
Actual results:

Expected results:

Ok, panics or hangs (ie, caps-lock flashing == panic) is a kernel bug.  What wifi hardware do you have, and what exact kernel version are you running?

You can run these commands to get that information:

uname -a
