--- Comment #33 from Alexandre Demers <alexandre.f.demers@gmail.com> ---
I made an observation: the hang will happen sooner when I play a movie.
However, playing a video is not needed to hang the system, it just happens
quicker. It happens only usual tasks (usually when switching of window or when
scrolling in a window). I know to have tracked it that the performance level
changes a lot when a video is being played depending of what else is going on.
So, I tried something: I forced performance level to "high". By doing so, I had
no crash (daily tasks, launched a quick piglit run, started TF2). I then force
performance level to "low" and then I did pretty much the same thing without
any problem.
So it seems the problem is not with a performance level per-se, at least not
with low and high. I would have to test with medium.
It could also be interesting to test UVD performance levels, which I doubt is
the problem since I can play videos and hangs happen even when UVD is not being
used or no videos are being played.
We could look at other things also. Maybe it is triggered after switching
performance levels soo many times or when doing some combination. Could we be
switching too often or too fast for the card?
Many questions to investigate.
