Demo
Hi,
by accident I found out that after some threshold on overdraw the GPU hangs. I
have attached a simple program that demonstrates the problem.

Overdraw application
I have fixed MIME for the overdraw demo. It requires Gtk+ 3.16 and it can be compiled by "clang main.c common/io.c `pkg-config --cflags --libs gtk+-3.0 epoxy`".

Overdraw GLFW3
This is a version using GLFW3 in case you do not have Gtk+ 3.16.
gcc common/io.c main.c `pkg-config --cflags --libs glfw3 epoxy`
Tesla card renders it correctly (it takes around 10 seconds), I will test on Intel (GL 2.1) when I get home.
Intel x4500 hang too, but seems to do better job at reseting.

| Resolution | --- | NOTABUG |
Hi Pavol, If the draw call takes more than 10 seconds, the kernel driver will conside= r it a hang and will try to reset the GPU, which might sometimes fail, leaving t= he GPU in an unusable state. I will close this as NOTABUG. Please try again with a lower instance count = and make sure it finishes in 10 seconds.
(In reply to Marek Ol=C5=A1=C3=A1k from comment #8) > I will close this as NOTABUG. Please try again w= ith a lower instance count > and make sure it finishes in 10 seconds. Alternatively use the kernel parameter radeon.lockup_timeout=3D20000 to inc= rease the timeout to 20 seconds.
