Do not e-mail me directly.

Report it.

Good, please try today's wireless-testing or compat-wireless and report if you
still see the issue. If not one gets back to you just reply again to the
thread and notice that you are still seeing the issue (if you are) on
current wireless-testing.

If you are seeing an issue with a stable kernel release then report
a bug on the kernel.org bugzilla.

Refer to logs with a URL.

Do not let this discourage you. Developers tend to not have
as much patience as you wish for, specially since wireless-testing
is bleeding edge and users are expected to at least be able to
report oops messages properly without much hand holding. It seems
to me Pavel was very patient with you.

make sure you have the latest wireless-testing, if you've applied any patches
on top of it make sure to clear them first:

git checkout -f

and then pull the latest changes:

git pull

Please refer to the git guide for more:

http://wireless.kernel.org/en/developers/Documentation/git-guide

With today's changes this means your git describe should spit
out something like:

mcgrof@tux ~/wireless-testing (git::master)$ git describe
v2.6.31-rc5-30113-gf1aa58f

If you don't see that you don't have the latest wireless-testing.
Another indicator if you are on the latest-wireless testing
is the last commit you see via 'git log'. Today this should be:

Once you are certain you are on the latest wireless-testing build it,
install it, and then report the oops you said you were seeing. If
you are not seeing an oops then chances are its been fixed or it
was only a compat-wireless bug. Either way issues should be reported.
