Solution: Debian error with iwlwifi

Having problems with the iwlwifi driver? Having cpu spikes? I have the solution which removed the problem for me.

My distro is: Debian Unstable 2.6.26-1-686 on a HP Compaq NX 7400

My /var/log/messages log keeps giving me this:

So if you wont need the wireless card, simply disable it:
