This is v 1.28 of sched_ule.c. Kernel configuration is basically "GENERIC" with a few device drivers removed, and "options HZ=250" and the nvidia kernel module. Symptoms are that jobs no longer appear to be placed on the run queue, they do not respond to 'kill -9'. I tried with a ordinary "nice make buildworld" which does not display these symptoms.
