I added this patch to the Fedora rawhide kernels, but our Fedora QA
lead reports that he still has this crash:
http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=233011
I had diagnosed this to be the same crash as this patch was supposed
to address. Was I in error?
He also reports that the problem still occurs on my FC7 test kernels,
which are very close to the current rawhide kernels but with the most
recent round of wireless-dev updates added.

Any thoughts?
