[Xen-devel] Linux 3.4 dom0 kernel error loading xen-acpi-processor: Input/output error

[Pasi Kärkkäinen <pasik@xxxxxx>]

Hello,

Does anyone know why loading xen-acpi-processor driver fails like this?:

# modprobe xen-acpi-processor
FATAL: Error inserting xen_acpi_processor 
(/lib/modules/3.4.32-6.el6.centos.alt.x86_64/kernel/drivers/xen/xen-acpi-processor.ko):
 Input/output error

Using "modprobe -v" doesn't provide any more information about the problem.
Also there's nothing in dom0 kernel dmesg.

Hardware is Dell R510 server with Intel Xeon 5600 series CPU. 
Xen 4.2.1.

Kernel is based on 3.4.32 (so the upstream kernel.org longterm stable version) 
with some additional Xen patches backported from later upstream kernels. 
Any tips how to troubleshoot this?
