    fails to boot all together; nothing on the serial console.

    on the working .32 kernel:

    # cat /sys/devices/system/clocksource/clocksource0/current_clocksource
    pit
    # cat /sys/devices/system/clocksource/clocksource0/available_clocksource
    pit

    just to be sure, I tried clocksource=pit on the .33-rc1 kernel. It didnt make
    any difference.
