Public bug reported:
Having upgraded from Karmic to Lucid, the iwl3945 driver no longer works on
this laptop. Under karmic, perhaps every 1-2 days the wifi system would die
with a 'Microcode SW error'. The fix was to disable wifi, 'rmmod iwl3945',
suspend the laptop for some seconds, resume, re-load the iwl3945 module and
re-enable wireless.
Under Lucid, the wifi system dies immediately on boot and the former fix no
longer works. I've had a look at the various bugs of this sort in launchpad and
other places. This is definitely not related to heavy network loading - this
laptop has not been able to connect to wifi since I put Lucid on it this
morning.
