Comment 21 for bug 271706

I also have a HP Pavilion zv6000 and am seeing this issue. As the other bug reports may indicate, after the volume maxes out it will start to flicker. After pressing the buttons some more I can get the OSD to disappear, but now none of the GNOME menus will drop down (they do highlight though). I got out of this by pressing my power button and selecting reboot from the pop-up options.

I'm running the released 8.10 64-bit desktop with updates.

If there's anything I can do to help please let me know.
