That is a good pointer, I will start experimenting with kdbrate and see
if anything improves.
I did come up with the following contraption which helps at least seeing
what is going on and so far
it seems that the password is 1 char short on invalid attempt and it is
usually the last char that seems to be missing.
I will probably figure it out through testing eventually.
#!/bin/bash
MAX_ATTEMPTS=3
attempt=0
while [ "$attempt" -lt "$MAX_ATTEMPTS" ]; do
printf "ZFS load-key password (attempt $((attempt + 1)) of
$MAX_ATTEMPTS): "
PASSWORD=""
while true; do
char=$(dd bs=1 count=1 2>/dev/null)
if [ -z "$char" ] || [ "$char" = "$(printf '\n')" ]; then
break
fi
printf "*"
PASSWORD="${PASSWORD}${char}"
done
echo "$PASSWORD" | /usr/sbin/zfs load-key -a
if [ $? -eq 0 ]; then
echo "Password accepted. Exiting."
exit 0
else
echo "Incorrect password. Please try again."
FIRST="${PASSWORD:0:1}"
LAST="${PASSWORD: -1}"
LEN=${#PASSWORD}
echo "Got $FIRST ... $LAST, length $LEN"
attempt=$((attempt + 1))
sleep 3
fi
done
echo "Maximum attempts reached. Exiting."

I can type the same password fast and it is wrong, then I type it very slowly
the third time and it works.
I feel like it must be some weird thing with the boot terminal input rate or
key detection but I have no clue where to start looking.

Any clues welcome
Hi,
I have experienced something similar, so it does not sound weird to me.
So my solution to my similar problem, might be a useful clue for you :)
I have a Toshiba Satellite Pro laptop [1] whose default keyboard rate settings
cause manual typing of the cryptsetup password entry in the initrd environment
to fail more often than not. A very annoying situation.
I fix this situation by causing /sbin/kbdrate to run inside the initrd
environment,
before the cryptsetup password entry occurs.
A while ago I wrote an email message about how I do that here:
https://lists.debian.org/debian-user/2022/01/msg00105.html

Maybe this method can help you with your encrypted ZFS password entry,
I don't know.
