Hi,
[clockevents: i386 drivers patch] introduces
irqbalance-does-not-work-properly problem.
(The irq is not distributed to two Core
,most of the irq is distributed to CPU1)
Mr. Thomas Gleixner,
any idea to fix this problem?

> [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.
