Arch64 auto reboot on rc.sysinit

Question

I use multi-boot system, both ArchLinux and Windows 2003 server were installed.
Whenever my windows partition is dirty ( required to do chkdsk ),   my archlinux can NOT successful boot.
It is always automatic-reboot during the boot  on the rc.sysinit, i insert some check point, it hangs between 'L4' and 'L5'.
---- some lines in /etc/rc.sysinit
stat_busy "Mounting Local Filesystems"
read -t 2 -p "L1:" x
/bin/mount -n -o remount,rw /
read -t 2 -p "L2:" x
/bin/rm -f /etc/mtab*
read -t 2 -p "L3:" x
# make sure / gets written to /etc/mtab
read -t 2 -p "L4:" x
/bin/mount -o remount,rw /
# re-mount /proc , /sys  and usbfs so they can be written to /etc/mtab
read -t 2 -p "L5:" x
umount /proc/bus/usb
read -t 2 -p "L6:" x
if [ -e /proc/mounts ]; then
        grep -e "/proc " -e "/sys " -e "/dev " /proc/mounts >> /etc/mtab
fi
I'm wonder why the mount -o remount will to checking my ntfs and caused my system hang.
(I have already set ntf's partions as noauto in /etc/fstab).

I forgot to said. Even on arch64's boot cdrom, it also have such problem.
That forced me must recover my windows partition at first.
