Subject: [Bug 69723] GPU lockups with kernel 3.11.0 / 3.12-rc1 when dpm=1 on r600g (Cayman)

--- Comment #60 from Martin Andersson <g02maran@gmail.com> ---
Instead of triggering the power level switches by running GpuTest in bursts, I
put this in a bash script:
for i in {1..3600}
do
echo low > /sys/class/drm/card0/device/power_dpm_force_performance_level
sleep 1
echo high > /sys/class/drm/card0/device/power_dpm_force_performance_level
sleep 5
done
and just let GpuTest, and piglit, run continously. I found that this also
trigger the lockups within minutes.
Then I ran the script by itself, no GpuTest or piglit, and left it running
while I was at work. When I came home the machine was still running, so it ran
for six hours without any lockup. So it seems the power level switching alone
is not sufficient to trigger the lockups, it also needs a load of some sort.
