limit all state

More errors with invalid access to 0. Looks like residual state from the earlier context. What happens if you apply the attached to xf86-video-intel?

Wasnt entirely sure what I was meant to do (havent strayed away from provided binaries so far)
I cloned the xf86-video-intel git repo, applied the diff you sent, ran an autogen, make and sudo make install, then restarted X, is that correct?

Could you please add more information about this bug, platform, feature, HW and SW information?

Hmm, if you were not careful that installed into /usr/local/lib/xorg which may not be picked up. If you check Xorg.0.log, it should contain a statement along the lines of "SNA compiled from git-..." that will match git describe. If not, try again with ./autogen.sh --prefix=/usr.

Have not run into the problem since applying the patch, so I think it may have fixed it.
