Pinebook pro crashing when put to sleep?? [Manjaro]

[edward]

Do you not know how to install packages?  On the bottom bar, to the right is a shield
When there are upgrades it is red, click on it, open package manager
control f (to find), type  downgrade, click button to put a check on install, bottom right apply, password
OR,, you could install from terminal,,, sudo pacman -Sy downgrade
Then open a terminal, any will do,,, alt space, when box opens at top type konsole, enter
then,
sudo downgrade linux,,, a menu will appear, pick a number
Yes, the new kernel causes s3 to fail to wake

It only shows "Firmware (gnome-firmware) 3.36-0-2"
Is that the one I should choose?

also apparently "downgrade" is not identified by my console, says "command not found". gonna install the downgrade from package manager and try again now...
[update] nope, still says "downgrade: target not found" and "downgrade: command not found"

sorry if my question is borderline mentally handicapped because it's probably piece of cake for guys like you, but I'm still very very new to linux, as eager as I am to learn all about it.

thanks in advance
