The problem is not with iwlagn as I see the same problem with b43.

There are at least 3 regressions in the latest version of Linus's tree. The
first is bad commit 9cb610d - it inhibits loading of modules from initrd and the
system will not boot. I'm bisecting the second - a NULL pointer BUG. Once that
one is located, I'll scope out the one you found. I know that commit 45e36c1 is
after the problem.
