--- Comment #2 from Zach Ploskey <zach at ploskey.com> ---
This issue is still present in 10.1-RC2. Entry of the GELI passphrase always
fails on the first try if the passphrase is entered after the password prompt
appears but, at least partially, during kernel output. If I wait for ~10
seconds for all the kernel output to stop, enter some backspaces for good
measure, and then proceed to enter the passphrase, it will work on the first
try.

Is the console device input somehow being invalidated by kernel output? How can
that be prevented? Can either the kernel output or the passphrase prompt be
delayed until the other has completed?

I'm not sure how many other people this bug may affect, but I am willing to
test patches if people have ideas.
