USB Regression in 8.0-R and 8-Stable

[Elliot Finley]

I have a server that's been running 7-Stable for along time.  It's set up
with geli at the disk level and ZFS (including root) on top of that.  It
boots from a USB key.  While booting it asks for the geli passphrase for
each disk.  This worked as expected in the 7-Stable branch.  In 8-Stable,
when trying to type in my passphrase, it drops random keystrokes.  To be
able to boot the system, I had to make the passphrase visible so that I
could re-type the keystrokes that were being dropped.

Is this a know issue?  If not, what information can I gather to help debug
this?
