Comment 9 for bug 1556965

Given the nature of this bug (sporadic, not easily reproducible),
identifying the bad commit by booting intermediate kernel commit
revisions could possibly be *very* time-consuming. This problem
affects my main desktop at work. I am not sure that I can invest that
much time to help identify this problem now.

As far as I am concerned, I am happy that my problem can be resolved
by using a more recent kernel. If it is very important for the Ubuntu
community that this problem gets fixed by backporting the good commit,
I may reconsider.
