Bug Description
[Impact]
Mesa 10.5.x suffers from a GPU hang on Skylake HW, bisected fix in 10.6.x:
commit 74fd226e34d0cf5
Author: Ben Widawsky <email address hidden>
Date: Wed Mar 25 16:52:46 2015 -0700
i965/skl: Don't use the PMA depth stall workaround
the system freezes soon after, causing loss of data.
[Test Case]
* installl chromium version 41.x (webgl disabled on later versions)
* open https:/
* grab the ship, rotate quickly
* should freeze in a few seconds
[Regression Potential]
* none, it's a gen9 specific workaround
