Public bug reported:
I am using an up-to-date Jaunty system on an IBM ThinkPad X60s.
When I boot my notebook with wireless turned off (using the killswitch),
the wireless cannot be enabled by just turning off the killswitch.
The dmesg output below is from booting system with wireless turned off
and then turned on once logged into GNOME:

The problem can be worked around with "rmmod iwl3945 && modprobe
iwl3945":

This worked fine (ie. without the workaround) with Intrepid and earlier
Ubuntu releases.
