[Problem]
With xscreensaver set to random, once in a while it freezes for a couple seconds, recovers, and then displays the Apport window to report the lockup.  The i915_error_state file and dmesg indicate that a GPU lockup occurred, but the system recovered.

[Original Description]

commit c501ae7f332cdaf42e31af30b72b4b66cbbb1604

    drm/i915: Only clear the GPU domains upon a successful finish
    
    By clearing the GPU read domains before waiting upon the buffer, we run
    the risk of the wait being interrupted and the domains prematurely
    cleared. The next time we attempt to wait upon the buffer (after
    userspace handles the signal), we believe that the buffer is idle and so
    skip the wait.
    
    There are a number of bugs across all generations which show signs of an
    overly haste reuse of active buffers.
    
    Such as:
    
      https://bugs.freedesktop.org/show_bug.cgi?id=29046
      https://bugs.freedesktop.org/show_bug.cgi?id=35863
      https://bugs.freedesktop.org/show_bug.cgi?id=38952
      https://bugs.freedesktop.org/show_bug.cgi?id=40282
      https://bugs.freedesktop.org/show_bug.cgi?id=41098
      https://bugs.freedesktop.org/show_bug.cgi?id=41102
      https://bugs.freedesktop.org/show_bug.cgi?id=41284
      https://bugs.freedesktop.org/show_bug.cgi?id=42141
    
    A couple of those pre-date i915_gem_object_finish_gpu(), so may be
    unrelated (such as a wild write from a userspace command buffer), but
    this does look like a convincing cause for most of those bugs.
