--- Comment #19 from eebfrasn-bugreply at usa.net ---
Did 'git pull' (commit e4ef6e9e5b2c8b637356621c60b28d064d40d29c) and tested
again, running with stock Ubuntu 14.4 kernel 3.13.0-85-lowlatency.

So far working fine with SNA acceleration mode. The newly built driver passes
the 'blender resize' test (running blender and quickly resizing its window
repeatedly).

FYI: my previous test (when it was failing was with commit bc8c161 - quite a
while ago).

I still have the "pipe_off wait timed out" kernel warning during startup,
though this was said not to be related to the present bug.

NOTE the Ubuntu package was also updated in the meantime, but I have not yet
tested whether it works in SNA mode. I will test it and post a separate update
here.

In any case, I will leave my workstation in SNA acceleration mode and with the
manually-built driver from GIT
(https://cgit.freedesktop.org/xorg/driver/xf86-video-intel/) to see how it
behaves - I put plenty of rendering load on it, so it should flush out any
problems quickly.
