This firmware error dump is useful. Thanks!

iwl3945: iwl-3945-rs not selected as rate control algo!

Can you try using the iwl-3945-rs rate scaling algorithm instead of
rs_simple? (at this moment, try loading iwl-3945-rs before rs_simple, it
will be fixed later). It increases performance a lot. Not sure about
stability though.

Thanks,
