This can indicate a problem with the filesystem is throwing errors.
Your root filesystem is typically mounted with an 'errors=remount-ro'
option, meaning the drive is remounted read-only if an error occurs.
The other possibility is that it's never getting remounted writeable
during the boot process, when running /etc/init.d/checkroot.sh, also
often because of filesystem issues.
Check your system logs and/or 'dmesg' output for any errors.

OK.
Watch your boot process carefully. Try booting single user ('single' at
your GRUB/LILO prompt, after the kernel spec) and manually go to
multiuser mode (just exit the admin shell).

Triple-check your autofs config. If that's the change, try disabling it
and seeing if the problem disappears.
Peace.
