CPU overheating and breaking is not uncommon for LCA based systems like Multias. Btw.: At least some if not all Multias have powermanagement features. If anyone is willing to test a -current patch I will implement it. You need a Multia or NoName with an 21066A CPU. Be aware that NoNames are usualy shiped (e.g. mine) with plain 21066 CPUs which don't have these features. -- B.Walter COSMO-Project http://www.cosmo-project.de ticso@cicely.de Usergroup info@cosmo-project.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
