Not consistent? Could you be more specific? Some git magic I forgot again?
This time I used git bisect to go through "merge" commits properly.

I did test countless times those commits: that would mean this TSC code would
"side-effect" an ultra-rare bad condition into an nearly-all-the-time bad
condition. That amount of bad luck?

Whatever, I'll update amd-staging-drm-next, and go through a full bisection
again. I'll need probably days (lucky: I don't work).
