On recent FreeBSD versions, I am observing unusual load averages reported by 'top' even when 100% idle. It happens in a normal system, in single user mode, and on official usb install images. I have not yet confirmed if the load is real or if it's just kernel reporting the values wrong. Here are kernels that I have tried. Four of them are from the currently available usb memstick installers; the 2011 one is a version I've been successfully using for a year until downgrading recently. 8.3-RELEASE amd64 2012-04-09 -> load 0.02 after 5 minutes idle 9.0-RELEASE amd64 2012-01-03 -> load 0.02 after 5 minutes idle 10.0-CURRENT amd64 2011-11-12 (cvs) -> load 0.02 after 5 minutes idle 9.1-RC3 amd64 2012-10-30 (r242324) -> load 0.60 after 5 minutes idle 10.0-CURRENT amd64 2012-11-02 (r242464) -> load 0.60 after 5 minutes idle >How-To-Repeat: 1) boot system on affected hardware(?) 2) leave 'top' running for a few minutes 3) observe load averages >Fix: >Release-Note: >Audit-Trail: >Unformatted:
