Hotspots are visible and are working OK but wifi card can't connect.

I'm just tested 3.9-rc2 and have the same problems (including
dma map warning). So I don't need debug logs for that.
However still I would like to see 3.8 logs from Zdenek.

Just checking, this problem reported above is independent from the DMA
map warning, right?

( I tested with 3.9.0-0.rc3.git0.3.fc19.i686.PAE :

Hit this bug also, on the GNOME-3.7.90.iso (based on FC19 testing
ISO), "Can't stop Rx DMA." and friends.

iwl3945 was/is working fine on 3.8.

Krzysztof Kolasa, you may want to see

requested debugging procedure for the problem.

Actually not, but patch I posted should fix both those problems.

Patch should be applied on 3.9-rc4 ...
