And regarding "just hit the enter key ... and all is fine", this
behaviour does not just occur at a login prompt. If you login quickly
as root to a minimal install as I often do, this behaviour occurs
during root console use, and if one is half-way through typing a
command which suddenly disappears from view, pressing enter could be a
recipe for disaster.
(eg dd before I have added the count= parameter).
So my habit when it occurs has become to: ctrl-u, enter, ctrl-y.
Between that and kernel messages barfing into the terminal text, it's
a pretty shitty user-experience that is embarrassing when observed by
users of any other OS.
