dmesg snippet from mesa 10.0.1
When I try to run some OpenCL code from within X the screen freezes, goes
black, goes on again while still frozen, ... this repeats a few times till it
won't come back again and all I have left is my monitor in standby and my
keyboard not reacting to any input.
When I try to run some OpenCL code from a console (Cntrl + Alt + F1) and go
back to X while the OpenCL code is still running it's the same as above.
When I try to run some OpenCL code from a console and go back to X after the
OpenCL code is finished I have a black monitor with my mouse cursor (I'm even
able to move it) for a few seconds, then my desktop is back. While it produces
the black screen (with mouse cursor) there's also GPU hang logged to dmesg.
Reproducable with bfgminer or the tests from
<a href="http://cgit.freedesktop.org/~tstellar/opencl-example/">http://cgit.freedesktop.org/~tstellar/opencl-example/</a> with mesa 10.0.1 as well
as 10.1 (git-646c16a).</pre>
