gdb backtrace

Using latest xf86-video-intel git, xorg-server 1.6.0 and kernel 2.6.29-rc7 without KMS.

Playing any video with xine leads to X server crash.

< anholt> kalev: ah, we need a pin/unpin implementation for fake bufmgr

Err, I guess I didn't have enough information on irc.  You do have GEM enabled, so you're not using the fake bufmgr.

This is probably a regression in the XV changes, I'm guessing.

I was experiencing these crashes as well. After reverting
 commit beca598bc2848093b710bd47828d622205d273df
 Access the Xv buffer through the GTT for the non-KMS case.
 commit 872aadc7102bd5131e1582ede081e22672911ba2
 Make Xv used a buffer object instead of i830_memory.
XV is usable again.
