Created attachment 127368 [details] 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.
I'm actually suspecting an hardware fault based on the fact that the bug persists over multiple kernel versions and the proprietary driver. I RMAed the card and am waiting to hear back. I will inform you.
I got my money back from the retailer. Therefor I think I can assume a hardware defect was the case. So this bug can be closed.
