--- Comment #16 from Hin-Tak Leung <htl10 at users.sourceforge.net> ---
I finally had a lock-up with mesa 10.2.9. Looking at the logs, I have had a
fair number of GPU faults which I did not notice, briefly for a few seconds
about 4 hours before an extended period of 1/2 hour of such faults. I believe
in the 2nd period I was watching a video with mplayer. (the first period might
be a trial run of the same video). I suspended the machine to RAM, then on
waking up, the screen flashed a few times between black and the last desktop
look, with some corruption in the desktop look; the mouse is still responsive
to movement but
clicking no longer works, nor keyboard (trying to switch to a vt to
shutdown/reboot, did not respond).

Anyway, I am onto mesa 10.3.4 now, which includes
http://cgit.freedesktop.org/mesa/mesa/commit/?id=ae4536b4f71cbe76230ea7edc7eb4d6041e651b4
. I hope this get fixed properly though, since the change looks like it just
band-aided over something.
