    time_init() is called before slab is set up. We cannot do memory
    allocations inside time_init().

    hrm. Looks like none of your testers have HPET_ID_LEGSUP hardware. This:

    --- a/arch/i386/kernel/hpet.c~a
    +++ a/arch/i386/kernel/hpet.c
    @@ -376,7 +376,7 @@ int __init hpet_enable(void)


    - if (id & HPET_ID_LEGSUP) {
    + if (0 && (id & HPET_ID_LEGSUP)) {
    gets it working. It basically nobbles the hpet and the kernel chose the
    TSC clocksource instead.

    btw, if you want to know why I go on and on about crappy commenting, try to
    work out from the kernel source code what HPET_ID_LEGSUP is, and why it
    gets special treatment. It is not possible. This is not maintainable
