Hi Nicolai,

The hangs only happen with the radeon Kernel driver. Today I tested linux-4.8.8
with the radeon Kernel driver, with mesa-git and llvm-svn, and the system
hanged. However, setting up clouds did not make the Sim crash.
I'm yet to test X-Plane with radeon, mesa-git llvm-svn, and that environment
you specified.

-----------------

The crash mentioned on this bug only happen with the amdgpu Kernel driver. Last
time I tried I couldn't use this driver with regular/stable Mesa.

Setting up `MESA_EXTENSION_OVERRIDE='-GL_AMD_pinned_memory'` WORKS! :D Could
you explain what it does? Could you push a patch so users are not required to
run this environment manually?

Thank you very much for your support so far.
