This is very similar to previous bugs:
[1] https://bugs.freedesktop.org/show_bug.cgi?id=3D105317
[2] https://bugs.freedesktop.org/show_bug.cgi?id=3D104001
but not needed make any action for hung occurs. It happens immediately after
start  graphic mode in Linux.


1. install Fedora 27.
https://download.fedoraproject.org/pub/fedora/linux/releases/27/Workstation=
/x86_64/iso/Fedora-Workstation-Live-x86_64-27-1.6.iso
2. install latest MESA and LLVM
https://copr.fedorainfracloud.org/coprs/che/mesa/
3. build and install staging kernel with latest amdgpu driver
$ git clone git://people.freedesktop.org/~agd5f/linux --branch
drm-next-4.17-wip
$ cd linux
$ make clean && make bzImage && make modules
# make modules_install && make install

Reproducing issue:
1. Try to boot computer with the newly builded kernel.

Symptoms:
1. The system stop to respod.
2. All the LEDs on the video card showing the load start to glow.
3. The turbine on the video card starts to make a lot of noise.

In dmesg appears follow lines:
[drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout, last signaled
seq=3D1, last emitted seq=3D5
[drm] GPU recovery disabled.
