SDDM corruption 4.18.0-rc1

amd-staging-drm-next (since 21/22 August 2018)
didn't work any longer with my nice RX580

Latest working amd-staging-drm-next kernel was from 16th August 2018
#5024f8dfe478 (my testing for Huang Rui ray.huang at amd.com)
https://lists.freedesktop.org/archives/amd-gfx/2018-August/025332.html

On 22th August I got first SDDM corruption (see attchament) and
[   14.322826] [drm:amdgpu_cs_ioctl [amdgpu]] *ERROR* Failed to initialize
parser !
in dmesg with amd-staging-drm-next 4.18.0-rc1.
(see attchament) dmesg-4.18.0-rc1-1.g7262353-default+.log

Later (23th August) I saw SDDM corruption and
[drm:amdgpu_cs_ioctl [amdgpu]] *ERROR* Failed to initialize parser !
plus
[    3.487757] RIP: 0010:amdgpu_bo_gpu_offset+0x56/0x90 [amdgpu]
(see attchament) dmesg-4.18.0-rc1-1.g7262353-default+.log3


After Alex's upgrade to amd-staging-drm-next 4.19.0-rc1
I got SDDM corruption (see attchament)
and
[   14.439424] [drm:amdgpu_cs_ioctl [amdgpu]] *ERROR* Failed to initialize
parser !
(see attchament) dmesg-4.19.0-rc1-1.g7262353-default+.log-25.10

First 'bisect' attempt went nuts  'cause the big merge with Linus tree didn't
resolve.
Can't find my former amd-staging-drm-next tag (#5024f8dfe478, see above) any
longer ;-(
