Bug Description
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.

Hi jpiesing,
If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https:/ /wiki.ubuntu. com/KernelMainl ineBuilds . Once you've tested the upstream kernel, please remove the 'needs- upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs- upstream- testing' text. Please let us know your results.
Thanks in advance.
