If you do not know that, we can not know it for you.

Well, this deserves to be investigated. You can get help by enabling
early printk.

The important part of my message is that ACPI should be enabled, with
only ACPI-Processor disabled.

Two things:
- first the dmesg buffer may be too small for kernels with lots of cpus
and USB devices plugged, so you do not get all the messages, better use
a serial console, or network console.
- the fact that you do not see the SMI chipset found may mean that your
chipset is not supported in Xenomai's smi module. To enable its
detection, you have to add the proper PCI ids to the ksrc/arch/x86/smi.c
file.
