Are you able to prioritize getting this series merged? This has been a
problem in -next for over a month now and the merge window is now open.
I would hate to see this regress in mainline, as my main system may be
affected by it (not sure, I got a new test machine that got bit by it in
addition to the other two I noticed it on).

Cheers,
