Kernel crash with acpi_processor, cpu_idle and intel_idle =y
Hi everyone,
When I set CONFIG_ACPI_PROCESSOR, CONFIG_CPU_IDLE and CONFIG_INTEL_IDLE
to y then I cannot boot Xen; there is a crash. If I turn
CONFIG_INTEL_IDLE off then the boot goes well and, after dom0 has
booted, xenpm works and gives some sane output, see below. I have
tested this with kernels 3.2 to 3.4.6.
Is it impossible to use INTEL_IDLE with Xen? If this is a known issue
then maybe

[RFC PATCH] Exporting ACPI Pxx/Cxx states to other kernel subsystems (v1).
Hello,
The following patches are a solution to a problem we have encountered
when using the Xen hypervisor:
- Need Pxx/Cxx states to save on power consumption when using Xen (we
do want those datacenters to consume less power!),
- Also need to figure out the Turbo mode so that the scheduler can properly
boost a core for CPU bound guests.
In essence the Xen hypervisor requires that
