after cvs update ~7/9 (and again an hour ago), booting my ultra 2
stops at a --db_more-- prompt

Rebooting with command: boot -s

--db_more--

if i hit space here, it loops printing tabs (or is it spaces) forever.
is there a way around this, while (i'm guessing) debugger support is
being worked on?  tia.
