[Garrett Cooper]

    Just reporting the fact that nvidia-driver 195.22 is horribly
broken between r206173 and r208486 (my machine consistency livelocks
at X11 startup); the latest driver is still broken as well with the
same symptoms. I realize that's a huge revision difference, and I'll
definitely try and track down the root cause via a binary search, but
I wanted to make sure that other folks knew of the issue and don't
upgrade and their systems break horribly as well.
    I suspect that the locking changes are causing the issue, but I
don't have any hard data to backup my claim at this time.
Thanks,
-Garrett
