I mean the crash which you Xorg.0.log.old attachment indicate. I have
this crash even without DIR2. It was fixed recently. And your log file
also show me that DRI2 also not enabled in your setup. You can see this
line in you log file.

(II) AIGLX: Screen 0 is not DRI2 capable

If DRI2 is setup correctly, this line should not exist in you log.
The option to enable DRI2 have moved to serverlayout/serverflags,
you may need to update you xorg.conf.

The drm shows some bug here too, and resume from suspend is broken
with it.
