This is not correct. We are tracing this problem in our bugzilla. And it
is the open place. Much more people have used it for a much longer time
even before the kernel bugzilla existed. If you take a look at the bug,
you know how much effort we put on it:

Johannes' effort is great and should certainly be praised. But looking
down upon Intel's effort is nonsense. We suspected this alignment issue
in the very beginning. But the set of users helped us to debug with this
problem happened to have a different root cause than Johannes. Thus came
with the alignment BUG_ON assert put into the code in case other people
experience with it (unfortunately, it was a wrong one. As I had
appologized for this already.)

The problem should at least have two causes. Johannes had resolved one
of them. The other one (AFAICS) relates to be in an 11n AP environment
(no need to be associated with it) and takes longer time to reproduce.
We will keep tracking it whatever we you think us about it.

Thanks,
-yi
