Well, try rebooting with -HEAD a few times.

Also, try r250665 (my first set of patches that enabled better ps-poll
support) and r250664 (the revision beforehand.) See if you can
reproduce the issues with that.

I have a sneaking suspicion that doing more aggressive power save
handling in hostap mode is causing issues but I haven't yet narrowed
it down.
