There's a known (on the net) issue with hwclock accessing /dev/rtc causing
hangs on ASUS motherboards (A7V133 in this case).  To get around this,
CLOCKFLAGS needs --directisa added to it for those motherboards.  hwclock
is called both in /etc/rc.d/sysinit and /etc/rc0.d/S01halt ..     Without
it, the system will seemingly hang on startup or shutdown for no reason..

I've logged this against util-linux as that's where hwclock is from, but
this may be an issue with /dev/rtc in the kernel..
