Comment 374 for bug 252094

My results on an Thinkpad X60 - everything is back to normal with Kernel 2.6.30:

Ubuntu 9.04, kernel 2.6.30-020630rc3-generic:
EXA: pp-racer ~100 FPS, glxgears 1577 FPS equiv to intrepid with INTEL_BATCH=1
no hangs, suspend/resume works fine, console switching works fine googleearth usable but menus do not properly overlay the map pane - really good performance
UXA: pp-racer ~25 FPS, glgears 430 FPS, freezes after short time googleearth 5 visually perfect

Same system with Kernel 2.6.28:
UXA: pp-racer ~ 18 FPS, glxgears 358 FPS, Compiz usable but much slower googleearth OK Stable?
EXA: pp-racer ~ 10 FPS, glxgears 212 FPS, Compiz usable but slow googleearth menus not OK, Map incorrectly redrawn during ALT-Tab switching
