Haha, this ended up being the HHKB Professional 2 USB keyword that was
hooked to my desktop.  Even when not using it, it appears that the small
USB hub that is built in the keyword sends noise to the line and causes
garbage to appear on stdin...

I should probably de-solder that near-useless thing from this otherwise
fine keyboard.

Thanks,

Closing.

Hello,

It's something I've suffered for a while already on my desktop machine,
but I always assumed I was making a typo or something.

Today I confirmed that without first clearing the input buffer via
multiple backspaces strokes, the first LUKS passphrase (I have many
disks) *always* fail.

Perhaps some boot message or other text gets erroneously redirected to
the standard input and corrupts the user input.

Thanks,

Maxim
