You are correct. It appears I've got a rebase issue. I rebased Ubuntu
Karmic against linus git 4a390e07fc53ce9dd615d7b788e9ecc73f87ad94 and
find that  there is one extra commit when comparing the output of 'git
log --pretty=oneline drivers/net/wireless/iwlwifi/iwl3945-base.c' . The
last commit that touches iwl3945-base.c in the Karmic tree is 'iwl3945:
do not send scan command if channel count zero', which is totally
bizarre. If I look at the patches created by 'git log -p
drivers/net/wireless/iwlwifi/iwl3945-base.c', the patch that implements
'iwl3945: do not send scan command if channel count zero' is duplicated.
How can that be? Guess I'll keep digging.
