Comment 28 for bug 271706

Ben Schaffhausen said "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 am having the exact same problem on a Compaq Presario R4000 running the 32-bit version of Ibex. Hope this gets fixed soon.
