The might_sleep() warnings are due to our adding a might_sleep() check to a place where we've _always_ been illegally sleeping. So a bisection search won't tell you anything on that front. The "kernel BUG in migration_call at kernel/sched.c:4044!" is due to one of the scheduler patches. I thought Ingo and Rusty had a handle on that one.
