Thanks for a clear summary (and likewise, thanks to others for the
quick feedback).

There have been a few iwlwifi fixes upstream recently.  Could you
try[1] v3.2-rc5 or later?

If it doesn't work, there are even newer patches to try in linville's
tree, but let's ignore that and pester upstream in that case.

Hope that helps,
Jonathan
