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 in the problem scene's draw function.
