That second paragraph should read:
And that message was already in the first dmesg ... so the i8042 driver
already KNEW something was fishy, and hinted what I should do ... ?

Interesting ... triggered by "[ 0.278602] i8042: PNP: PS/2 appears to
have AUX port disabled, if this is incorrect please boot with
i8042.nopnp", I just tried i8042.nopnp as only option in GRUB, and that
works too: keyboard works immediatly.
And that message was already in the first dmesg ... so
Only i8042.direct ... not good. Keyboard not working for x seconds
Only i8042.dumbkbd ... yes, works! Keyboard working immediatly.
So my /etc/default/grub now contains:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.dumbkbd"
And stuff from dmesg:
sander@zwart2204:~$ sudo dmesg | grep i8042
[
Does it require both "i8042.direct i8042.dumbkbd" to work?

Title:
laptop keyboard not working for about 30 seconds after resume from
suspend
Out of curiosity:
The manual work (adding the line to GRUB): is that how it should be, or
a bug (something Ubuntu should take care of)?

Title:
Ah, SOLVED, like this:
Triggered by your remarks, I found
https://unix.stackexchange.com/a/656183, which says:
RUB_CMDLINE_LINUX_DEFAULT="atkbd.reset i8042.reset i8042.nomux quiet splash".
If this doesn't work, follow the same process but try
GRUB_CMDLINE_LINUX_DEFAULT="i8042.direct
I tried "i8042.noaux=1", but no change: after boot and after resume:
touchpad works immediatly, but keyboard takes 25-45 seconds.
dmesg included
** Attachment added: "dmesg "i8042.noaux=1""
Please give "i8042.noaux=1" a try, thanks!

To manage
Thanks for replying.
See included dmesg. I generated it with the following command ...
hopefully OK
sudo dmesg -T > dmesg_after_suspend_and_resume.txt
Snippet from dmesg:
[wo jun 1 11:38:40 2022] i8042: [28649] 65 -> i8042 (parameter)
[wo jun 1 11:38:40 2022] i8042: [28649] ab <- i8042
Please add kernel parameter "i8042.debug=1", reproduce the issue, and
attach dmeseg here.
** Changed in: linux (Ubuntu)
Status: Confirmed => Incomplete

Ah, it seems to happen after a fresh boot too: the login is there, mouse
is working, but keyboard not. It takes 20 - 30 seconds before keyboard
is working.
Snippet from dmesg (leaving out wlo1 stuff):
