Xorg log for a broken session

Sometimes Compiz won't start, and prints:

intel_do_flush_locked failed: Input/output error

This is usually (but not always) fixed with a reboot, but never by logging out and back in.

I use Compiz without a desktop environment on 64-bit Arch Linux, using a GMA 4500MHD.  Installed packages are xorg-server 1.13.0-4 and xf86-video-intel 2.20.14-1.

I've attached /var/log/Xorg.0.log for a broken session.
