--- Comment #1 from Alexander Mezin (mezin.alexander at 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
