Since we also have some experience in this, you might want to take our responses to indicate that your thinking may be in error. I'm certainly not trying to treat you like a yokel. I'm trying to get you to think and behave like a computer engineer with nearly 30 years of experience. So far this hasn't been very successful. > Well here's some data: > > FreeBSD 3.3-RELEASE #0: Thu Sep 16 23:40:35 GMT 1999 > jkh@highwing.cdrom.com:/usr/src/sys/compile/GENERIC > > (lmmon -i reports) > > Motherboard Temp Voltages > > 32C / 89F / 305K Vcore1: +2.016V ... > 41C / 105F / 314K Vcore1: +2.016V Is this the same lmmon binary in both cases?

The first step in resolving this has simply been to try to narrow down the variables so that we have some idea what might actually be involved here. It's been a painful process, but we're almost there. Once you can confirm that the onboard temperature sensors are working and bear a good resemblance to reality we can eliminate them from the equation. I did ask for verification of this (which hasn't been forthcoming yet). I've also asked you to undertake the second phase, which is to perform a binary-search set of kernel builds to pin down the timeframe in which this change occurred. It's also been suggested that the scheduler changes made by Bruce Evans may have impacted your system; you might want to bracket those changes to quickly eliminate them as possibilities. -- \\ Give a man a fish, and you feed him for a day. \\ Mike Smith \\ Tell him he should learn how to fish himself, \\ msmith@freebsd.org \\ and he'll hate you for a lifetime. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
