dmesg
When I compile xf86-video-intel with sna and using gnome shell it sometimes
freezes the whole Xserver. This happens approx once a day of normal usage and
so far I haven't found a reliable way to reproduce (just move windows between
workspaces a lot, maybe with opengl apps it may freeze faster but not sure). I
can't do anything, even switching to console doesn't work, however I can still
ssh in. All my attempts to obtain a backtrace through ssh were unsuccessful.
When i try to attach to X with gdb, it just freezes, the same happens when I'm
already attached to it at the moment of incident. There is some interesting
info in the dmesg. Also attaching Xorg log. (Logs are few days old, however the
incident just happened toady with bleeding edge stack).
BTW I was using UXA with no problems for a week. SNA lasts at most for 2 days.
