Thanks, these are all interesting (even if some of them seem to be
from random kernels).

Fengguang, is this a new script that you started running? Because I'm
*hoping* it's not that rc6 suddenly seems so flaky, and it's really
that you now have a nice new script that started reporting these
things better, even though many of them may be old?

This particular one I will have to leave to the intel gfx people to comment on.
