i'm running slackware64, with this packaged installed:
xf86-video-radeonhd-1.3.0-x86_64-2
xorg-server-1.9.5-x86_64-1
mesa-7.10.2-x86_64-1
libdrm-2.4.25-x86_64-1

and using the kernel 3.0.1 (mainline kernel, no patchs)

After i start the X11, all works fine, but past a few days i start o get some
errors on dmesg about AGP and GEM errors:

[381894.050008] [TTM] AGP Bind memory failed.

0x00000002)

and if i keep using the X11 without rebooting, sooner or later i get this
crash:
