Comment 1 for bug 204097

I would like to confirm.

 It's a bit hard to understand from the explanation above, but I think i have relatively the same problem.

After installing the latest updates on my hardy heron today (Mar, 22, 2008), I rebooted. Upon the boot-up the normal splash screen appeared, and soon underneath I noticed that in small orange letters it said it was doing a routine disk check (because it had been mounted 22 times). Which was OK, since I've seen it do a disk check with no problem before. However, at around 70% (maybe less), it stops and appears to hang. The system then proceeds to reboot. If left unattended the system will repeat this procedure and reboot indefinatley. The only way to avoid it, is to press ESC when it starts doing the disk check. That way it never hangs, and continues to boot normally.
