It's not crashing, it's exiting with an error. If you have passive cooling enabled, it can block powerd from setting a new rate (as it should). Are you running -current? If so, upgrade your powerd. I just committed some code that among other things, just gives a warning instead of exiting if it can't set the level. -- Nate
