Do you have the irqbalance daemon running? If yes, disable it and retry.
If it helps, you may also want to try

git://git.kiszka.org/ipipe.git queues/2.6.38-x86

If that doesn't help, try to disable CONFIG_DMAR (though it should left
off by default during boot) and CONFIG_INTR_REMAP.

Regarding CONFIG_HPET_TIMER: That's not selectable on x86-64. If you
have "enough" cores, the kernel will run out of HPET timers and won't
select them as clock events. With 8 cores, you should be safe, but
better check the kernel boot messages for "hpet" or the state of
/proc/timer_list regarding "Clock Event Device" when booting the same
kernel without Xenomai support.
