init q
tail -f /var/log/syslog

os erros que obtinha no wheezy:

getty[11492]: /dev/hvc0: No such file or directory - em auth.log

init: Id "co" respawning too fast: disabled for 5 minutes - em syslog

para resolver é necessário comentar em /etc/inittab a linha:
co:2345:respawn:/sbin/getty hvc0 9600 linux

this line is used for virtualization XEN, if you don't install debian in XEN then comment the line.
