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
http://www.spinics.net/lists/linux-wireless/msg104564.html on requested debugging procedure for the problem.

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 :

Mar 19 18:17:05 s2 kernel: iwl3945 0000:02:00.0: Queue 4 stuck for 2495 ms.

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

Patch should be applied on 3.9-rc4 ...
