Created attachment 582709 [details] Patch to fix this problem for devices with a single hardware queue This patch should fix the problem - at least it does for my systems. At the moment, it has not yet been incorporated in the wireless-testing tree, but that should happen soon. If you are able to test, please report success or failure.
Josh, please apply above patch as fix for this bug.
Hm. So it seems the reporter was using a self-built compat-wireless bundle. I'd be happy to apply the patch, but I wanted to make sure it's really needed on a 3.3.x stable series of kernels without compat-wireless. Also, has the fix been CC'd to the stable maintainers if so?
Ahh, ok this is fix fo commit 3a25a8c8b75b430c4f4022918e26fa51d557ecde Author: Johannes Berg <johannes.berg> Date: Tue Apr 3 16:28:50 2012 +0200 mac80211: add improved HW queue control queued for 3.5. That will be fixed upstream before we will start to use it.
