For what it's worth, adding the iwlwifi-5000-2.ucode to the builtin firmware list fixed the two BUG: messages related to the firmware load. Not sure if that tells you anything or not. However, I still have left: [ 0.997904] Monitor-Mwait will be used to enter C-1 state [ 0.998045] Monitor-Mwait will be used to enter C-2 state [ 0.998184] Monitor-Mwait will be used to enter C-3 state [ 0.998300] Marking TSC unstable due to TSC halts in idle [ 0.998476] Switching to clocksource hpet [ 1.030681] BUG: key ffff88011c8c1d00 not in .data!

I'll stick a 'WAR_ON(1)' next to that BUG printk so we get an idea where it's happening, probably be morning before that happens though... --==_Exmh_1268116039_4061P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Exmh version 2.5 07/13/2001 iD8DBQFLlepHcC3lWbTT17ARAi6YAKDzilj6k2PLfewHeMK97jWS/3dYWACfQYsN cVzS5A8rzkLiF9QY0c5YaDU= =lRGQ -----END PGP SIGNATURE----- --==_Exmh_1268116039_4061P--
