Strange,strange...


First of all try to boot with clocksource=acpi_pm
(I want to test whenever HPET working as clocksource is a problem)

Then try to boot with hpet=disable or unset CONFIG_HPET_TIMER
(This will disable hpet both as clock source and clockevent)

Please send also contents of  /proc/timer_list 
(I want to know whenever APIC timer is enabled there or not)
