full dmesg

We are working with a new consumer laptop based on Ryzen 7 3700U.

amdgpu device:

03:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.
[AMD/ATI] Picasso [1002:15d8] (rev c1) (prog-if 00 [VGA controller])

Upon suspend/resume (this platform uses s2idle), the pre-suspend image can be
seen on screen, but the display is totally hung. These kernel messages can be
seen in the resume process:

[  281.293412] [drm] PCIE GART of 1024M enabled (table at 0x000000F400900000).

This has been reproduced on Linux 5.2 and linus master as of today. As this is
a brand new platform there is no previous known working version. It does
suspend/resume fine under Windows 10.

Please let me know how I can help further. We'd be happy to ship a product
sample to AMD developers for diagnosis.
