So we need to bisect between 2.4.38 and 3.0.0? :)  I'm running ubuntu 
11.10 on a home laptop so I'll give this a try as well when I can if I can 
put up with unity for that long.

Hi,
Any results on this home laptop test yet? (Running kde-ubuntu here :) ).

I've bisected the problem and narrowed the bug to changeset 73b78a2272
(http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=73b78a22720087d2d384bdd49e9c25500ba73edd).

Here's a patch, that applies against 3.2-rc5, that fixed the error for me:

this is not right, you stop the bt coex for non-combo device.
maybe you system has issue with BT, we seen this happen on some cases.
try the following module parameter and see if help

$sudo modprobe iwlagn bt_coex_active=0

Thanks
Wey
