This is the same problem I'm seeing (See Subject: Regression in 2.6.22, clock problems on Turion with 32-bit kernel).
This commit is what we bisected to:
commit e9e2cdb412412326c4827fc78ba27f410d837e6e Author: Thomas Gleixner <tglx@linutronix.de> Date: Fri Feb 16 01:28:04 2007 -0800
[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.
