ubuntu-oneiric::arch/arm/Kconfig:

config HAVE_LATENCYTOP_SUPPORT
    bool
    depends on !SMP
    default y


unfortunately the check is at compile time so we can't do much about it.

Actually the problem seems to be related to CONFIG_STACKTRACE (a feature
exploited by latecntytop) that is not smp safe:

Closing here.
