Just reverting the commit -- that makes your machine work, even if it's

You're right, of course -- UMS is a huge wart on the kernel driver at
this point, keeping it working while also adding new functionality
continues to cause challenges. We tend to expect that most people will
run reasonably contemporaneous kernel and user space code, and so three
years after the switch, it continues to surprise us when someone
actually tries UMS.

Let me know; I've pushed this patch to my drm-intel-fixes tree on
kernel.org in the meantime; if it does solve the problem, I'd like to
add your Tested-by: line.
