I'm not currently running it for obvious reasons. I'll reboot and
check but i'm pretty sure it's called something like irq_timer not
actually irq 11 or anything like that. This is a single core, non-smp
system. I haven't got latency tracing enabled, but i'll recompile with
it and check.

Has anyone got it actually working on x86_64 though?
