when testing the following cases, GPU locked. First it stops responding for
some seconds and screen goes black, then it return to normal.
loop:vertex-step=5, fragment-steps=5, fragment-loop=false;
loop:vertex-step=5, fragment-steps=5, fragment-uniform=false;
loop:vertex-step=5, fragment-steps=5, fragment-uniform=ture;

I've already tried several radeon boot flags, such as DPM on and off,
radeon_lockup_timeout = 20000, without success. Upgrading the kernel version to
4.5.3 and 4.6.0 but it not fixed. 

The problem does not occur when i add a delay（such as 1ms using msleep） in the
problem scene's draw function.

I thought is the  problem of Synchronization between the cpu and gpu using
fence , can anyone have some idea?

Did this also happen with older versions of Mesa and/or the kernel?

I've done the test with Mesa 10.3.0 (xorg-server-1.16,libdrm-2.56) and
kernel-3.14, the GPU lockup does not occur. 
I've also tried with Mesa 10.3.0 and kernel-4.4, the GPU lockup still not
occurs. So It looks like it have a relationship with the mesa.

I guess I may be to have a try, but not in the last few days as it will cost a
lot of time. 
Are there any other reasons cause this problem? Thank you very much for your
reply，Could you give me some advice or anything else about it?

--- Comment #5 from Tiger <tigerliu.ee@gmail.com> ---
So after two days of testing, I found this bug is still present in mesa-11.1.2.

The GPU lockup does not occur after i tested several times with 11.0.2 on my R9
270/HD 5450/HD 7450, but locked up on E6760.

11.1.2 or 11.2.0 + kernel-4.4 = lockup (HD7450,5450,r9-270)
11.0.2 + kernel-4.4 = No problems! 

That looks more like some patches from commit  
51e0b06d9916e126060c0d218de1aaa4e5a4ce26(11.0.2) to commit     
7bcd827806b0816d61122ba3d37dd40178d96d98(11.1.2) introduced this bug and
triggered by 'glmark2 -b grid'. 

I want to use 'format-patch' to pick the patches from 11.0.2 to 11.1.2, can
anyone provide a classification of the patches or some critical patches to me
to locate. I don't have a in-depth understanding of the Mesa.

Furthermore, I'll try the latest Mesa for some times and report back if I
either get a gpu lockup, or don't.

git bisect makes this a lot easier. If you don't know how to use it yet, search
for "git bisect howto".

Always use VRAM for PIPE_USAGE_STREAM buffers, the GPU lockup does not occur.

Does setting the environment variable R600_DEBUG=nowc for the glmark2 process
avoid the problem?
