Sounds like interrupt remapping is enabled for your system. That's not
supported by Xenomai / I-pipe so far (on my to-do list, along with
x2APIC support). Disable this via "intel_iommu=off intremap=off" in the
kernel command line or by changing the kernel config to not include
IOMMU / interrupt remapping support.
