Sorry, one more clarifying point here:
When you used either clocksource=hpet/clocksource=acpi_pm did the behavior of the system seem different after booting? In other words: does running time waiting a few seconds and then running time again show the expected passage of time? Were any following hangs seen, or was it only the first one at boot?
