I'm having the same issue which I reported here: https://bugs.freedesktop.org/show_bug.cgi?id=75494 I was under the impression that EXA doesn't work with radeonsi? On my machine enabling EXA disables direct rendering with Xorg.log complaining that "Screen 0 is not DRI2 capable" so the suggested workaround doesn't really work.
Of course DRI is not working. At least there are no crashes with "EXA" enabled and 2d performance is pretty normal. gtkperf: GtkDrawingArea - Lines - time: 1.32 GtkDrawingArea - Circles - time: 2.56

Please attach the output of dmesg after the crash. Can you get a backtrace of the crash with gdb? Note that there is no EXA support for Southern Islands and newer Radeons, Option "AccelMethod" "EXA" just disables all hardware acceleration with those.
Created attachment 95527 [details] dmesg after the crash
Fixed since I've updated kernel to 3.14rc7.
