Trying out ULE scheduling on an SMP machine causes background processes
to be stuck in locks.

One or two processes will always get stuck in *Giant (and takes up like
60% of lock) and if these are killed, then other processes are always
taking up a total of around 10% in lock, which makes the system crawl.

Anybody else seeing this on an SMP machine with ULE scheduler?
