[Intel-gfx] 945gm: xrandr crashes X
Hi, after upgrade to 2.6.34 kernel I'm unable to configure external VGA monitor anymore, any attempt to use xrandr results in X crash with following message: X: intel_bufmgr_gem.c:900: drm_intel_gem_bo_unreference_locked_timed: Assertion `((bo_gem-refcount)-atomic) 0' failed. There's a bug entry in gentoo bugzilla, however they blame xorg-server, but xorg-server-1.8.x works for me with 2.6.33.x kernel: http://bugs.gentoo.org/show_bug.cgi?id=318743 Is it known/fixed issue, or should I file a new bug on fd.o bugzilla?

Instead of swapping bos, swap the entire private structure. 2. If we update the pixmap bo for the Screen, make sure we update the reference inside intel-front_buffer so that xrandr still functions.
