--- Comment #21 from James Zhu (jamesz at amd.com) ---
Hi Jeromec, to isolate the cause, can you help run two experiments separately?
1. To run suspend/resume without launching Xorg, just on text mode.
2. To disable video acceleration (VCN IP). I  need you share me the whole dmesg
log after loading amdgpu driver. I think basically running modprobe with
ip_block_mask=0x0ff should disable vcn ip for VCN1.(you can find words in dmesg
to tell you if vcn ip is disabled or not).

Thanks!
James
