Bare with me here as I'm totally new to FreeBSD (like 2 weeks). >From what I understand, there is a change in FreeBSD 9.1 ACPI code that makes detection of devices happen earlier? This can result in eventtimer irqs being shared with another device and can therefor throw off tools reporting load avg values (they report constantly around 0.60 in load). I guess there were good reasons for making the ACPI change, so is this a ACPI problem or should the code around the tools, such as top, change? This is a 9.1 "regression" as the problem is not there in FreeBSD 9.0. Here's some more info on the bug and possible workarounds: http://www.freebsd.org/cgi/query-pr.cgi?pr=173541&cat= and http://lists.freebsd.org/pipermail/freebsd-stable/2012-April/067382.html Any input on this would be greatly appreciated.
