For a while now, some screensavers sometimes lock up my machine. That means all screens go blank, the keyboard is unresponsive (numpad-key doesn't toggle the indicator led), the sound loops. But I still can use ssh from a remote machine and the magic-sysrq-keys also work. There is nothing to see in neither /var/log/messages (acquired via netconsole) nor /var/log/Xorg.0.log. I can trigger the bug (or regression, I think it used to work about 2 months ago) reliably by using the Xfce4 screensaver settings application, which has a preview of the screensaver selected. When switching between screensavers, the lockup quickly occurs. A good candidate is the screensaver named "AntMaze", it alsmost always locks up my machine (only worked once so far). Other stuff works quite solid, Half-Life 2 worked multiple hours today. Setting R600_HYPERZ=0 in /etc/environment didn't help. Also occurs on kernel 3.8.0-rc7. I'm happy to provide more info if needed.
