I did some research as to why fvcool would make your computer unstable. And, it turns out, it is not so much the CPU itself which may cause instability, but the power supply. :( The idea is, that when your power supply heavily fluctuates between, say, 70W (normal operations), and 5W (power-safe mode), the power supply may experience trouble keeping the voltages stable. Plus, rapidly fluctuating the power draw, to the effect that fvcool would cause, or rather: that power-safe mode would cause, it is argued that the lifespan of your power supply may shorten drastically. And then there is the issue of the UPS. Dunno about others, but my UPS (APC 350), according to its specifications, does not allow equipment that draws power on a gliding scale (like lamps with dimmer switches). All-in-all, and I say this with regret, I have therefore decided not to use fvcool, after all. :( - Mark To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message

The other thing to do, depending on whether you can take the machines offline (how many are there?), is to get a better heatsink and fan properly mounted on the CPU, and determine whether you can improve internal ventilation with case fans. -- Jud To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message

FreeBSD and AMD power management
I have noticed that my Compaq IA-1's (AMD K6-2/266 VIA chipset) run substantially hotter under FreeBSD than under Linux. I didn't realize just how much until the machines began spontaneously rebooting under load. Right now, I have a minimal 4.7R install (with X) running from a microdrive - but I don't have problems until I start running X for long periods of time. I am migrating from Midori linux with kernel rev 2.4.18, and it can go for weeks (even months) running xmms locally.

I have noticed that FreeBSD accesses the microdrive a *lot* (though Linux may be as well, but I can't hear it because it's running from flash) Is this a normal limitation in FreeBSD, or did I miss something in the kernel config?
