When reloading the iwl3945 driver I often get this:

Note that I used antenna=2 parameter to experiment with quality of reception of both antennas
(this feature strangely works just fine....)

I disabled this option, so next time I feel like rebooting my system, I see if this option was the cause.
(unlikely)
