It's a Gigabyte 6BXD with 2xPIII 550MHz processors. I can provide other information if necessary about the hardware, but it's nothing too exotic. The problem I'm having is that although the kernel seems to work fine, and tools like "top" report that the CPUs are idleing, after a few minutes the system starts getting really warm, and eventually the BIOS thermal alarms are triggered at 65 degrees C. As I say, despite this it is all fine in operation, and processes on both CPUs are ok. It is clearly running way too hot though. I've checked my hardware out, and it's all ok. It's working cool in Linux, so I think there's something in my kernel that I need to sort out. What I was wondering was is this a known problem? Can it be fixed? Any other ideas? Thanks, your help is much appreciated. Cheers Michael Wells To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
