** Description changed:

  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.
