This started with F13 and hasn't been fixed in F14. It's always the same message and I kept uploading the kernl oops but nothing happened. so I'm trying to post it here.

if you need any information I'll happily try to give it!

To get rid of that errors we had to rewrite iwlwifi scan code. That rewrite will not be backported to F-14. All related bugs should be fixed in F-15.

If that problems bothering you, try compat wireless 2.6.37 or newer
