I've also experienced this bug, so this is more of a confirmation of
this problem on another system.

Running xserver-xorg-video-ati 6.6.3-2 on my system with DRI enabled
causes the X server to hang in some kind of loop. Keyboard and mouse
are unusable, but the system is still up, and remote logins to it are
still possible. The X server process consumes as much CPU as it can
get, and is not killable. A reboot is required to return the system to
a usable state.

The graphics card is a Asus A9250GE/TD/256M/A.

(I haven't attached full log files since this is just to confirm the
same problem others have reported. Please let me know if you need

The problem can be worked around by changing the AGP Aperture BIOS
setting. Changing this from 32MB to 256MB let me enable DRI. (As
suggested by https://bugs.freedesktop.org/show_bug.cgi?id=6111#c30)

Motherboard is Asus TUV4X, which uses a VIA Apollo Pro 133 chipset,
according to agpgart.
