If you are trying to reduce power consumption, why are you limiting Cx
states to C2 (which save little) and not C3 (which will save a LOT of
power when the CPU is not heavily loaded).
With my hardware, i5-650, using C3 does not result in lower power consumption
versus C2. Both states draw

How can it possibly provide any thermal benefit, if it does not
reduce power consumption? Is there some significant heat source,

On my previous post I forgot to set kern.hz=100. This change does lower idle
power from 71w to 62w.

Hello Ian,
I'm also facing same problem, just updated to esxi 5 update1, will
see if it changes anything.
It really looks like an esxi problem but I did not experienced it

I've already updated to the latest BIOS and this could have caused the

Sorry, what I was getting at was that a bad bios (eg latest could have
introduced a regression) can cause the symptoms you are seeing.

Hi,
one of my FreeBSD 8 i386 server runs in a reboot loop after updating
/sys/boot/i386/gptboot/Makefile from 1.62.63 to 1.62.6.4 (rev 230162).
Several amd64 machines with the same Makefile for gptboot work fine.
This issue was discussed for FreeBSD 9 some weeks ago in freebsd-current.

On one of my FreeBSD 9 machines, 'cdcontrol eject' works fine but
'cdcontrol close' fails. Any ideas on the cause? (I have never seen
anything like this on other machines, in any FreeBSD release.)
Starting from the closed tray and seeing a successful physical eject:
