You didn't read /usr/src/UPDATING. The problem you are seeing is covered in 

        The scheduler framework has grown a second scheduler and consequently
        you must specify one and only one scheduler in your kernel config.
        The cvs config files have been updated to use the old scheduler
        which may be selected via 'options SCHED_4BSD'.  If you would like
        to try the new, much more experimental, scheduler please try
        'options SCHED_ULE' and contribute to the arch@ discussion.

You probably should add  'options SCHED_4BSD' to your kernel config file.
