I doubt its anything to do with spinlocks, but this issue is going to be
much easier to figure out if it occurs on a freshly booted machine with
just a dom0, no xend (hence no bridge).

Please can you confirm that this is the case. Is it just the timer
interrupt line that's going up fast?
(BTW: what is ioc0?)

Exactly what kernel are you using? Have you modified the config?
What hardware are you using (including any USB devices)?

Thanks,
Ian
