I have just tried to boot with the suggested kernel params then ssh in
the system and "modprobe amdgpu". I have tested 2 cases: 1) not logged
to X; 2) logged to X
Both cases seem to behave about the same:
- screen turns all black and cannot be recovered (rmmod amdgpu)
- system itself keeps

There are no entries in the journal for those particular boots I'm
afraid. That is, the journal is empty if I boot without "nomodeset" or
without "amdgpu.ip_block_mask=0xfdff". There are some very quick
boot messages appearing on the screen before it turns all black, but
nothing in the log.

Use `journalctl -b -1 -k` to collect kernel message from last boot.

Status
Dear Kai-Heng, I'm not quite sure what you actually want me to try ...
but Kernel 5.12-rc8 with "nomodeset" & without
"amdgpu.ip_block_mask=0xfdff" gives:
- amdgpu kernel module not loaded, Xorg amdgpu driver not loaded
- Xorg vesa driver loaded & no acceleration => high CPU load
- suspend
In theory Xorg modesetting driver should just work, and the kernel
parameter is not necessary.

ACP disabled

The problem I reported here was NOT fixed by the latest kernel update
(5.4.0-71).
To clarify what I observe on my AMD-based desktop:
The suspend/hibernation/resume problem seems to be strictly related to the
amdgpu kernel module and possibly also amdgpu Xorg driver. I have tested the
following
Second problem (freeze after suspend/resume) seems to be fixed with
5.4.0-71-generic.
