Bug detailed description:
-----------------------------
Run bin/fp-indirections2 -auto, It randomly causes <3>[  223.918559] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... blitter ring idle.
It happens 1 in 10 runs on Haswell with -fixes kernel. Run 10 cycles on -queued kernel, it works well.

output:
Max TEX instructions / TEX indirections: 1024 / 1024
PIGLIT: {'result': 'pass' }

Reproduce steps:
----------------------------
1. xinit
2. bin/fp-indirections2 -auto
Comment 1 Jesse Barnes 2014-06-05 20:59:47 UTC 
Is this a kernel regression?  Sounds like a GL bug...
Comment 2 Daniel Vetter 2014-06-18 14:19:28 UTC 
Nope, blitter ring idle means the kernel missed an interrupt somewhere. Not a mesa bug.
Comment 3 Daniel Vetter 2014-06-18 16:14:15 UTC 
Hm, could be the semaphore check gone wrong though. Can you please retest with latest kernel?
Comment 4 lu hua 2014-06-19 06:09:32 UTC 
Test 15 cycles on latest -nightly kernel, it works well. Close it.
Comment 5 Elizabeth 2017-10-06 14:38:03 UTC 
Closing old verified.
