            Bug ID: 108781
           Summary: 4.19 Regression - Hawaii (R9 390) boot failure -
                    Invalid PCC GPIO / invalid powerlevel state / Fatal
                    error during GPU init
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: critical
          Priority: medium
         Component: DRM/AMDgpu

dmesg (journalctl) of failure on 4.19.2.arch1-1

arch 4.18.16.arch1-1 works, using kernel parameters:

 radeon.cik_support=3D0 amdgpu.cik_support=3D1 amdgpu.dpm=3D1 amdgpu.dc=3D1

Upgraded to 4.19.2.arch1-1, and started getting this failure.  Going back to
4.19.arch1-1 still gives this failure.

Full dmesg (journalctl) attached for 4.19.2.arch1-1 (failing), 4.19.arch1-1
(failing), and 4.18.16.arch1-1 (working).  But pertinent part of failure is
below for search.

This failure occurs booting to a tty, so no X logs are involved.  (You might
see on 4.18.16.arch1-1, there is a [drm:generic_reg_wait [amdgpu]] error and
backtrace which has been happening forever, but it works and doesn't cause a
noticeable problem.)
