Comment 1 for bug 127927

Hi! Thank you for taking time to report this bug and help us make Ubuntu become better.
It took me a while to realize that you were able to type commands after the message "can't access tty, job control turned off".
It is important to understand that this message come for many many different errors.
I have actually open a new bug about this message: bug #129612.

Rather than typing 'modprobe ata_piix; exit' I would suggest you type:
cat /var/log/casper.log and looks for error message.
(Actually, the real error message have probably be shown on screen, just a bit before the "can't access tty, job control turned off")
This is the real problem that need to be fixed and caused busybox (just a shell to type commands) to be called because the
system was not able to continue loading normally.
