Upstream suspects this may be a case of
http://bugs.freedesktop.org/show_bug.cgi?id=7128, due to the
AIGLX code dereferncing a stale DrawablePtr.
** Description changed:
Binary package hint: xserver-xorg-video-radeon
When attempting to run a 3d game such as Enemy Territory or a game via
wine X crashes and locks up. I am still able to ssh into the system but
unable to kill X in any way. Exactly the same thing happens using the
kernel from Hardy so I'm inclined to believe this not a kernel issue.
dmesg is entirely filled with:
