It looks like dimitry has already resolved the issue. To answer your question however: yes there is an inelegant way to disable est/speedstep and some of the other frequency/voltage scaling technologies on i386 and amd64 boot into ddb and write a large value to global setperf_prio e.g.: boot -d ddb> w setperf_prio 666 ddb> cont Code that honours the priority will bail in its init routine. gwk
