Hi! This is a surprisingly long standing problem with a RX 460, more precisely since 4.15 all the way up to 4.18 AMD staging DRM next [1]. After resuming from sleep (echo -n mem > /sys/power/state) amdgpu is dead (always, reliably). Here's what dmesg has to say about it: [Sun Jul 8 11:01:17 2018] PM: suspend exit [Sun Jul 8 11:01:19 2018] [drm:gfx_v8_0_ring_test_ib [amdgpu]] *ERROR* amdgpu: IB test timed out.

[Sun Jul 8 11:01:19 2018] [drm:process_one_work] *ERROR* ib ring test failed (-110). [Sun Jul 8 11:01:28 2018] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout, last signaled seq=864, last emitted seq=868 [Sun Jul 8 11:01:28 2018] [drm] GPU recovery disabled. >From ealier versions: [ 42.802559] PM: suspend exit [ 42.824332] amdgpu 0000:41:00.0: GPU fault detected: 147 0x0bd84802 [ 42.824338] amdgpu 0000:41:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x0034F97B [ 42.824341] amdgpu 0000:41:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x0C048002 [ 42.824345] amdgpu 0000:41:00.0: VM fault (0x02, vmid 6) at page 3471739, read from 'TC0' (0x54433000) (72) [ 52.956306] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout, last signaled seq=1287, last emitted seq=1289 [ 52.956316] [drm] IP block:gfx_v8_0 is hung! [ 52.956362] [drm] GPU recovery disabled. I've also seen fault 146 but other than that it mostly looks the same. 4.14-lts (with dc=0) works fine. RX 460, Zenith Extreme, 1950x. [1] arch linux AUR; this versioning is a bit confusing, it may actually already be the 4.19 branch, latest commit is3838e387fd1eb17bfcf6ff7d443d931adb5cb41b
