macbook pro suspend to ram broken in linux-2.6.git HEAD

[Soeren Sonnenburg]

a rather long git bisect session between v2.6.20 and HEAD identified the
commit below this as the cause. please note that the machine does not
return from resume and although all PM debug was turned on there is
nothing in the logs. happens with a minimalistic setup (console only no
audio/network etc) without SMP and CONFIG_HPET_TIMER  but PREEMPT on and
CONFIG_ACPI=y
CONFIG_ACPI_SLEEP=y
CONFIG_ACPI_SLEEP_PROC_FS=y
CONFIG_ACPI_AC=y
CONFIG_ACPI_BATTERY=y
CONFIG_ACPI_BUTTON=y
CONFIG_ACPI_VIDEO=y
CONFIG_ACPI_FAN=y
CONFIG_ACPI_PROCESSOR=y
CONFIG_ACPI_THERMAL=y
CONFIG_ACPI_BLACKLIST_YEAR=0
CONFIG_ACPI_EC=y
CONFIG_ACPI_POWER=y
CONFIG_ACPI_SYSTEM=y
CONFIG_X86_PM_TIMER=y

Any ideas on that issue ?

    [PATCH] clockevents: i386 drivers
    
    Add clockevent drivers for i386: lapic (local) and PIT/HPET (global).  Update
    the timer IRQ to call into the PIT/HPET driver's event handler and the
    lapic-timer IRQ to call into the lapic clockevent driver.  The assignement of
    timer functionality is delegated to the core framework code and replaces the
    compile and runtime evalution in do_timer_interrupt_hook()
    
    Use the clockevents broadcast support and implement the lapic_broadcast
    function for ACPI.
    
    No changes to existing functionality.
