Yes, I'm not seeing any change here either. So, I don't think that we
have a locking or ordering issue. Are the effects on shutdown a
problem? I think it may have more to do with the fact that we have
released memory before we have switched display modes on shutdown. I
can reproduce the strange color effects on this i915, but haven't hit a
case where it created any sort of problem.
