Ubuntu's kernel team provide some helpful texts about getting more
informations out of the crashes: (a bit of a hassle)
https://wiki.ubuntu.com/KernelTeam/CrashdumpRecipe
https://help.ubuntu.com/community/DebuggingSystemCrash

but maybe you can save you some time:
1. if possible update your compat-wireless
   a crash bug (affects compat-wireless, wireless-testing and even -rcX series)
   has been fixed. This bug is known to strike on configurations with a
   high number of auth/assoc/deauth - cycles.

2. Quintin Pitts had/has problems with the reliability of his
   p54pci <-> pci-bus and wrote a patch:
       http://patchwork.kernel.org/patch/53004/raw/

    unfortunately for him, his pci-bridge is known to be faulty,
    but maybe he found some real bugs after all.

3. replace firmware:

yeah, normally you can see such phenomena when you have a funky AP and 
enable wifi powersaving... but this is unlikely, as the ps is disabled
(can be enabled with iwconfig wlanX power on) for this reason.

can you please tell me more about your AP?
e.g: Product Name, Vendor, firmware revision,
is it 802.11 a/b/g/n, is WEP/WPA(2) enabled, or is it just an open ap?
