I frequently hibernate or standby my computer when I leave my seat during office hour.

With this build 479, sometimes it freezes just before windows logon shows up. So the screen is black, but the power bulb is on, I need to press the power button to “force” shut down, and then everything is ok after restart.

And today I test it with cache disabled, the “freeze” disappeared.

My system is winXP, 2GB ram, cache as 256MB system ram and 4GB SD card.
