            Bug ID: 109628
           Summary: WARNING at dcn10_hw_sequencer.c:868
                    dcn10_verify_allow_pstate_change_high()
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: zajec5@gmail.com

I use HP EliteBook 745 G5 with Ryzen 5 PRO 2500U and external monitor BenQ
GW2260.

Today after taking ~10 minutes break amdgpu had some problems with enabling my
external monitor back (after putting it in sleep mode or something). It took it
about half a minute I think.

I checked dmesg immediately and found there a WARNING:
[65984.999696] WARNING: CPU: 6 PID: 2081 at
drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_hw_sequencer.c:868
dcn10_verify_allow_pstate_change_high+0x25/0x260 [amdgpu]

I suspect it may be related to the issue I'm reporting.

So far I was using kernels 4.19 and 4.20 (for the last 2 months) and never saw
it. A day ago I've switched to the kernel 5.0.0-rc6. It may be either:
1. A regression
2. A very rare bug
