    top has to deal with the fact that the userland priority only applies
    while running in user mode, so it could be reporting bad values.  If
    you are getting scheduler related hangs you should still be able to 
    ctl-alt-esc into ddb> and do a 'ps' and 'trace'.  If you can't break
    into ddb it probably isn't the scheduler.

    If you can reproduce a priority related hang (other then using rtpri to
    create a high priority user process and spinning it) post it.
