Not sure which one of those :-

LD [M] drivers/acpi/processor.ko
LD [M] drivers/xen/acpi_processor.ko

I believe second one causes issue under Xen 4.0 Hypervisor

Can you make that be a module instead? And when the machine has booted
up, try to load the module (you might need to rename the modele to say
processor.ko.old so that udev won't automatically load it)?

And also compile the kernel with CONFIG_ACPI_DEBUG=y and
CONFIG_ACPI_DEBUG_FUNC_TRACE=y

Lastly, when you boot your machine, please add these flags
to your Linux kernel command line:

acpi.debug_level=0xffffffff acpi.debug_layer=0x2 initcall_debug
