Comment 172 for bug 541492

Passable stability with drover git716, random screensavers cycle for several hours, with eventual freezes on open GL (implying that perhaps upgrade to Mesa 7.8.2 might be in order). Upon freeze, X does not crash, and desktop can be recovered, however, attempting to open the screensaver control panel will crash the system. On other occasion, X will be brought down (green light on monitor, X cannot be recovered), or system will be brought down (monitor indicates no signal). In either event system is working well under applications such as google Earth. Lucid solution is close, hopefull this will be fully resolved in Maverick. (I can assure that i815 system works flawlessly with perfect stability on current git716 driver)
