I'll compile a kernel with CONFIG_NO_HZ to see what happens but how do I
disable cpuidle during boot? I've checked the kernel-parameters.txt but
there's no cpuidle related boot parameter there.

Booting with intel_idle.max_cstate=0 should do the trick.

intel_idle.max_cstate=0 causes a fallback to the acpi_idle driver. So it
does not disable the C-states directly.

What about not building the acpi_idle driver, then?

Or just use the processor.max_cstate parameter then.

As I wrote a couple of messages ago, https://lkml.org/lkml/2011/1/31/52 .

Sure, that should do the trick too.

Thanks,
Rafael
