Subject: PROBLEM: iwlagn kernel 2.6.32.3 ooops

  Hi, 

This ooops happens on kernel 2.6.32.3. On a .32.7 it didn't 
happen yet. Maybe fixed, maybe not.

Keywords (i.e., modules, networking, kernel):
iwlagn, kernel 2.6.32.3


Below two msgs:
The first is the ooops that occurred when using the box as usual (IRC: after 
this crash no rmmod && modprobe have been possible).

The second - IRC - when the iwlagn module crashed, rebooted, crashed differently, 
was then removed after the different ooops and re-modprobed.
