**Using SCHED_ULE on SMP/HT machine broke applications which use libpthread/libthr, probably at context switching between threads... The applications simply hang and they aren't killable (kill -9 <pid> don't work).. Usually this also break kernel shutdown (can't flush some inodes or blocks)... This is very big problem for people who want use mysql_server on SMP machines... On FreeBSD 5.4-RC3 this don't happend...
