Hi Chris,
I tested a browser case with latest UXA code and experienced X crashed.
I bisected it and found that it was introduced by
commit 5d5b2b8ee203ae2274fc7d13ed38d2945facca9e.
The back trace of the crash is as below:

It's a one line patch. And there is not too much thing to do with UXA code,
I guess It may be a libdrm related problem.
It's can be simply reproduced in my machine, Use Mozilla 3.6.10 to open the
following URL:
http://pnp.sh.intel.com/WRTBench/Workload_3.3_rev0.13/iterations_rev11_new.h
tml
It will iterate many pages and finally give a report. The crash may occur
after a few seconds of running.
Uncomment that one line patch can avoid this crash.
