--- Comment #1 from Alexander Mezin (mezin.alexander@gmail.com) --- Just tested 4.15.15 and 4.16 On 4.15.15 suspend and resume works fine On 4.16 the system freezes even with amdgpu.dc=0
Note that Arch has
CONFIG_DRM_AMD_DC=y CONFIG_DRM_AMD_DC_PRE_VEGA=y # CONFIG_DRM_AMD_DC_FBC is not set CONFIG_DRM_AMD_DC_DCN1_0=y
in kernel config for both 4.15 and 4.16
