I have tested the latest mainline kernel:
```
$ uname -a
Linux Zveri2 5.16.0-051600rc5-generic #202112121931 SMP PREEMPT Mon Dec 13
00:36:00 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
```
No changes.
I agree that this might be an ACPI issue. On startup, I see the
following messages with this kernel:
```

I didn't check if there are changes compared to older linux packages.
The messages repeat for \_SB_.PLTF.P000 to \_SB_.PLTF.P00F. The BIOS is
updated to the latest version available.
I think @Ping-Ke Shih refers to classic pm-suspend behaviour vs the new S0ix
sleep. I used the bash script from here:
https://01.org/blogs/qwang59/2018/how-achieve-s0ix-states-linux to test S0ix
compatibility of my laptop, and found that there is no support for S0ix at the
moment:
```
ACPI: WSMT 0x0000000000000000 000028 (v01 _ASUS_ Notebook 01072009 AMI
00010013)
Acpi Data Table [WSMT] decoded
Formatted output: wsmt.dsl - 1314 bytes
Low Power S0 Idle is 0
The system does not support S0ix!
```
I can add the full output if necessary.
Using either `systemctl suspend` or `pm-suspend`, the computer's
behaviour doesn't look different to me.
While googling I found this message in LKML:
http://lkml.iu.edu/hypermail/linux/kernel/2107.2/02226.html , and
judging by https://bugs.launchpad.net/amd/+bug/1928694 the fix should be
in kernel 5.10. Though my CPU's architecture is Renoir, it seems no S0ix
for me is available yet.
