Description Mark Janes 2016-12-09 17:15:46 UTC 
BYT intermittently report the following dmesg error when executing piglit:

   Unable to purge GPU memory due lock contention.

Subsequently, the machine fails other GPU test suites, and eventually hard-hangs.

I've performed hundreds of piglit runs on byt to reproduce this intermittent issue.  The earliest I have seen it is:

029e8ff81c65c2e0562be4a5d93fe83a9df49233
radv: Initialize the shader_stats_dump flag.

It's likely that this is triggered by a i965 commit just prior to 029e8ff.  I will continue to test in an attempt to identify the regression more precisely.
