By the emails I received regarding my SMP system running really hot even in idle state, I've understood that FreeBSD's SMP code runs all CPU's at full speed, and never utilizes the HLT instruction on them. Why doesn't the SMP code use HLT? Is there any work in progress to get the SMP code in FreeBSD to use the HLT instruction? Or is there some trick to get the HLT instruction to work even in SMP? My system is definately not working to good right now, overheating, random crashes, etc.. Of course not just caused by FreeBSD's SMP code, but also bad physical cooling (which I'm working on..). /Johan _________________________________________________________ En adress för livet registrerar du på http://www.home.se/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
