[Bug 1849084] Re: Freeze on system-resume caused by kwin and amdgpu driver

[khitschler]

Please note the lines
* Feb 16 15:47:43 Lin kernel: [drm] pstate TEST_DEBUG_DATA: 0xB7F60000
and
* Feb 16 15:47:43 Lin kernel: [drm] pstate TEST_DEBUG_DATA: 0x37F60000

(I've cut the repeating parts)

The lines are emitted in the kernel source code at
../drivers/gpu/drm/amd/display/dc/dcn10/ by the function
hubbub1_verify_allow_pstate_change_high()
