dmesg output

I'm having random system freezes with my Amd R9 380X. The freezes happen under
3d load maybe once a hour.

This happens on both Arch (linux 4.7) and Ubuntu 16.04 (4.4 with backports).

The freeze itself produces no output (nether kernel nor any other log) but I
just found that after 2 min the kernel will produce a hung task info. (See
attachment)

The freeze affects all graphical output: No mouse movement or switching to
virtual terminal. The rest of the system still works.


Please let me know of any debugging steps I can try.
