completely frozen system after group handshake

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):
Steps to Reproduce:
1. wlan connection with wpa
2. using firefox
3. after a while the system crash
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:
Linux fedora 18.104.22.168-170.2.35.fc10.x86_64 #1 SMP Mon Feb 23 13:00:23 EST 2009 x86_64 x86_64 x86_64 GNU/Linux
