This is believed fixed in mesa-10.5.3.
My system is updated. So, why i am facing this kind of behavior. So, can it be, that fixed is not pushed to live version.
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.
Dear Reporter, This Mesa bug has been in the "NEEDINFO" status for over 60 days. I am closing this bug based on lack of response but feel free to reopen if resolution is still needed. Please ensure you're supplying the correct information as requested. Thank you.
