Hi Likun, Sorry if you don't want emails like this. I added info. to https://bugs.freedesktop.org/show_bug.cgi?id=110258 but people on Gentoo forums said email would be better. Git bisect lead me to you: --------------- 106c7d6148e5aadd394e6701f7e498df49b869d1 is the first bad commit commit 106c7d6148e5aadd394e6701f7e498df49b869d1 Author: Likun Gao <Likun.Gao@xxxxxxx> Date: Thu Nov 8 20:19:54 2018 +0800 drm/amdgpu: abstract the function of enter/exit safe mode for RLC Abstract the function of amdgpu_gfx_rlc_enter/exit_safe_mode and some part of rlc_init to improve the reusability of RLC.

The problem occurs with all kernels since 5.0 up to and including 5.3-rc2. My laptop is: HP 15-bw0xx cpu:AMD A9-9420 RADEON R5, 5 COMPUTE CORES 2C+3G with integrated graphics: Stoney [Radeon R2/R3/R4/R5 Graphics] [1002:98E4] There are several similar reports on the web, most or all for Stoney hardware, but that might be a coincidence as laptop users are more concerned about suspend, and there are a lot of laptops with similar integrated graphics motherboards. I'm running Gentoo with a custom kernel, the most relevant bits of the config CONFIG_DRM_AMDGPU=y # CONFIG_DRM_AMDGPU_SI is not set # CONFIG_DRM_AMDGPU_CIK is not set # CONFIG_DRM_AMDGPU_USERPTR is not set If you tell me how, I'm willing to try to collect traces etc. Paul Gover _______________________________________________ amd-gfx mailing list amd-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/amd-gfx
