Hi David,
I'm not sure I understand what the problem reported is but I don't think a DT
patch could be the cause of a locking issue on x86.
If I missed something, feel free to let me know.
Cheers
Jerome

Hi Jerome,
I think you are right. It seems that other unrelated kernel bugs have
diverged bisection into the wrong direction.
