What happens if you add clocksource=acpi_pm and nohz=off to the kernel

Hmm. Nothing really obvious.

Then the kernel boots and it seems to work.


If you want I can build an debug kernel and boot with initcall_debug or anything else may help to find the problem,

Sorry, this thread slipped out of my attention.

Is this still true with 2.6.25-rc5 ?

Thanks,
