<pre>What exact version of Mesa do you have?
Looking at your error state, it appears that we're hanging on a CONSTANT_BUFFER
packet while a WM_STATE is bound with "PS Uses Source Depth". I didn't check
CC_STATE to be sure, but this looks to be the exact known hang.
I see no workarounds for the issue in your command stream. Mesa 10.5.3+ would
try to insert an MI_FLUSH, but apparently the conditions were not triggered to
make that happen. I see no 3DSTATE_GLOBAL_DEPTH_CLAMP_OFFSET commands either
(save the one at the top), so you're clearly not running Mesa 10.6.x.
Mesa 10.6.x contains what I believe to be the actual correct fix for this bug
(commit f55ded764ce60f87463e33bfa3a32e2c44715581). Please try that.</pre>
