Hello friends.
Suspend to RAM on Amlogic A311D chip (Khadas VIM3 SBC) was broken with
5.17.13 and with 5.18.2 it also presents.

When I trying do this I recieve error message:

With 5.16.2 kernel version suspend to RAM is working, but system very
slow after resume.

Can you use 'git bisect' to track down the offending commit?

And does 5.19-rc1 also have this issue?

thanks,

Yes, I can finding broken commit, but it may requiring lot of time
with my system.

5.19-rc1 suspending successfully, but at resuming kernel freezing. Is
big core frequency not small?)

New kernels freezing after resume only when scaling governor is
"conservative". Yes, I using this because my solar battery produce a
few of electricity. When scaling governor is performance system not
freezing after resume.
However, sometimes I received "Device or resource busy" error after
echo mem > /sys/power/state.
Later I found out what this was related with another bug:
pipewire-media-session is <defunct>, nosound and many processes which
using audio as mplayer, ffplay, alsamixer and etc was not responding
and not terminating even throught kill -9.
The log after alsamixer launch:

After I removed pipewire software "Device or resource busy" error was
disappear. But the sound and media still doesn't working and alsamixer
cannot change sound card to my usb audio device after commit
bbf7d3b1c4f40eb02dd1dffb500ba00b0bff0303.
