[Solved] iwlwifi very unstable after 3.4 upgrade (Centrino 1030 BGN)

Since the 3.4 kernel upgrade my wireless (iwlwifi, Intel Centrino-N 1030) has been extremely unstable and essentially unusable. There have been reports of problems on Intel 6x00 wifi cards, but I've not seen any on the 1030. I've tested this on 3.4.2 and 3.4.3.

The current workaround is to stay on 3.3.x kernel. A dmesg log is included below. It shows "Queue 2 stuck" and a firmware reload.

$ dmesg | grep iwl

Re: [Solved] iwlwifi very unstable after 3.4 upgrade (Centrino 1030 BGN)

I tried testing/linux-3.4.4-1, and the problem appears fixed.

There's a fix for in 3.4.4 for iwlwifi firmware version for 6000g2 (which is what the 1030 card uses). Marking as solved.
