(In reply to Andrey Grodzovsky from comment #10) > Created attachment 140418 [details] [review] [review] > drm/amdgpu: Verify root PD is mapped into kernel address space. > > dwagner, please try this patch. Fixes the issue for me and I observed no > suspend/resume issues. While I can start X11 with this patch applied to current amd-staging-drm-next, attempts to resume from S3 fail consistently. The following related output is emitted right before the suspend: Jul 02 21:31:32 ryzen kernel: Freezing remaining freezable tasks ... (elapsed 0.000 seconds) done. Jul 02 21:31:32 ryzen kernel: Suspending console(s) (use no_console_suspend to debug) Jul 02 21:31:32 ryzen kernel: sd 9:0:0:0: [sda] Synchronizing SCSI cache Jul 02 21:31:32 ryzen kernel: [TTM] Buffer eviction failed Jul 02 21:31:32 ryzen kernel: ACPI: Preparing to enter system sleep state S3 Jul 02 21:31:32 ryzen kernel: PM: Saving platform NVS memory Jul 02 21:31:32 ryzen kernel: Disabling non-boot CPUs ... (I wonder if that "[TTM] Buffer eviction failed" is a bad sign - as I have seen it some other times in conjunction with heavy uses of the amdgpu driver.) Then, upon resume, the following messages are emitted: Jul 02 21:31:33 ryzen kernel: ACPI: Low-level resume complete Jul 02 21:31:33 ryzen kernel: [drm] PCIE GART of 256M enabled (table at 0x000000F400300000).
