You're more confident about that than I am! It will be very satisfying if my patch turns out to make the difference, but still surprising to me.
Thank you for taking the time on this, Mark: I too would appreciate it if you could later determine whether it's new kernel or patch solving it.

I was adjusting the changelog and about to send direct to Linus Cc stable in a few minutes, since I'm guessing there might be a 33-rc6 today, which would be a pity to miss.
Whatever my reluctance to assume it's the fix to Mark's problem (which I'm not mentioning in the changelog), we are both sure it's a valid bugfix.
