I have a Ryzen 7 3700U in an HP laptop. lspci describes the GPU in this way: 04:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Picasso/Raven 2 [Radeon Vega Series / Radeon Vega Mobile Series] (rev c1) This laptop has never successfully resumed from suspend (I have tried every 5.x kernel). Currently on 5.18.0, the system appears to be okay after resume apart from the gpu which is usually giving a blank screen, occasionally a scrambled output. After rebooting, I see this in syslog: Jul 25 11:02:18 frog kernel: [240782.968674] amdgpu 0000:04:00.0: amdgpu: GPU reset begin!
