Hi,
Some recent commits (in last 2 days I guess) broke iwlagn driver.

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.

I met the same issue when applied patch-2.6.30-rc1 to kernel 2.6.29.
And I saw many "Call trace" in dmesg after system boot up.
Attached the log here, hope it could help.
Thanks,
