[Bug 105733] Amdgpu randomly hangs and only ssh works. Mouse cursor moves sometimes but does nothing. Keyboard stops working.

--- Comment #40 from John W. <kaiser at airmail.cc> ---
Is there any resolution or work being done on this issue?
I've tried the frequency hack and it slightly delayed the issue
I also tried the latest amd staging kernel with latest firmware and XF86 driver
and found the same issue still happened but somewhat less. Reading my
journalctl logs I found sometimes when it occurs it will attempt to recover but
in the process loses NRAM and freezes the screen covered in odd colors
At least when this occurs the machine is otherwise functional and I can change
TTYs and kill X11
I'm using a 580 and I've added the relevant logs of the attempted recovery.
