--- Comment #8 from Mit Matelske <[email protected]> ---
Sorry for the delay!  

I tried the patch out and sched_balance_group now runs but the I can still get
a process stuck in the RUN state on a busy CPU.  FWIW, it doesn't seem like
that mechanism ever moves processes.  All my calls to tdq_move comes from the
tdq_idled loop.

I'm debugging why the process doesn't get moved now.  Weird thing is other
processes are successfully getting moved from the busy CPUs from the tdq_idled
loop.  Just not the stuck process.

Don't know if this helps, but it seems like if I start another process,
something triggers and it will move the stuck process and everything will run
fine for awhile.  Any clues from that?
