Xorg.0.log of the crash
Sometimes when moving the mouse pointer between my main monitor (on first radeon RV770) and my TV (second radeon RV770), X will hang. Until now this always (3 times) happend after a few hours of normal usage. All graphics is frozen, just the mouse pointer quickly jumps between the screens. The computer still responds to ssh from outside, but the keyboard seems to have no effect anymore.
I use xorg-server 1.7.1, evdev, xf86-video-ati from git on the current drm-next kernel with KMS. OS is Gentoo Linux.
Attached is the Xorg.0.log after a crash.
Mass closure: This bug has been untouched for more than six years, and is not obviously still valid. Please file a new report if you continue to experience issues with a current server.
