--- Comment #5 from Andrey Grodzovsky (andrey.grodzovsky@amd.com) --- It's not a crash but a warning over invalid reg fields access - here https://elixir.bootlin.com/linux/v4.15.1/source/drivers/gpu/drm/amd/display/...
I see you are working with 4.15 kernel, can you take the latest stable from here - https://www.kernel.org/ and see if problem goes away ?
For quicker response time you can try submitting tickets to Free Desktop Bugzilla - https://bugs.freedesktop.org/
