https://bugs.freedesktop.org/show_bug.cgi?id=91278 --- Comment #47 from Andy Furniss --- Seems like you are using an old kernel - though what I call old may be current for what's released. The hanging for me stopped with 4.4, but 4.3 is release. If you are using 4.3 maybe booting with the option - amdgpu.enable_scheduler=1 will help. If you are used to compiling your own kernels then using one from - http://cgit.freedesktop.org/~agd5f/linux/ like drm-next-4.4 should be stable. Or if you want to test/use the new powerplay try amdgpu-powerplay -- You are receiving this mail because: You are the assignee for the bug.
