My machine is running 11.1, a two-disk ZFS mirror, and geli encryption. About a month or so ago I started seeing a case where once in a while after power-up, when I'm at the password prompt and I begin to enter it the baton doesn't jump to the right as it usually does. Entering the password anyway and hitting Enter just boots to the point where the password is requested for each of the two disks. Then everything proceeds as usual. It's as if I have partial keyboard, but just at the password prompt; 'Enter' always works as advertised. Hard power cycling always 'fixes' this but I'd like to know why the password prompt doesn't acknowledge input. I can boot so it does see the keyboard.
