It is a new behavior since 2.6.1-rc1-mm2. It hung in wait_for_completion() called from sched_migrate_task() called from sched_balance_exec(). The migration threads are not in the kgdb "info thread" list. It looks like they've already been killed. I can do some more debugging, but I'm hoping someone will own up.
