kernel log for s2both with s2idle (hybrid sleep): v6.0

@Mario

I've got another related problem.
(just tell me if I should open another bug for that)

The system doesn't correctly enter s2both with s2idle. (a.k.a. "hybrid sleep")
Instead the system seems to do simply a s2disk.
So the system simply shuts down completely. And resumes from swapfile at power
on.

Correct behavior would be to write the memory to swapfile (like s2disk), but
then enter s2idle.
(the idea behind s2both is to prevent data loss if the battery is getting
drained while being in some suspend to memory)



What I do:
echo suspend > /sys/power/disk
echo disk > /sys/power/state

$ cat /sys/power/mem_sleep 
[s2idle]

Behavior is independent of the settings in these files:
/sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0D:00/power/wakeup
/sys/devices/platform/i8042/serio0/power/wakeup
/sys/devices/LNXSYSTM:00/LNXSYBUS:00/ACPI0003:00/power_supply/AC/power/wakeup
/sys/module/acpi/parameters/ec_no_wakeup

Please see the attached kernel log.



I use s2both on a lot of systems, especially with AMD CPU+GPU. And it usually
works flawlessly. But these systems all use S3 instead of s2idle. And I
couldn't find if there's something extra to consider when using s2both with
s2idle.
