--- Comment #27 from org.freedesktop at io7m.com ---
New info:

The machine appears to be unstable even if dpm is disabled. I've no idea why
the machine didn't crash last time I tried without dpm. Using the profile based
switching and setting:

  # echo profile > /sys/class/drm/card0/device/power_method
  # echo high > /sys/class/drm/card0/device/power_profile

... causes the machine to become unstable within minutes (the screen flickers,
messages similar to that posted in my last message appear on dmesg). Sometimes
the screen will clear for a minute or so, but then start flickering again and
eventually the machine will reboot.
