and what's this line in your patched sched.c?

is it -- BUG_ON(!irqs_disabled());  ?

anything in your unposted code (e.g. find_coolest_cpu()) that might
re-enable the interrupts before __migration_task() is called?

If you post your modifications as a patch
(Documentation/applying-patches.txt) that contains _all_ relevant
modifications, it'd be easier to guess what's wrong.
