I think that the problem is that HPET and the CMOS RTC (list in CC)
share the same interrupt line.
I suppose that you should enable CONFIG_HPET_RTC_IRQ (my hardware has
the same "feature"); in this way /dev/rtc correcly reports that it
cannot deliver the interrupt (when HPET is enabled) and hwclock uses
direct ISA access.
I searched the CONFIG_HPET_RTC_IRQ, it's conflict with
HPET_EMULATE_RTC, that I've enabled.
so while HPET_RTC_IRQ is the good way, EMULATE_RTC is a bad way.
