freebsd stable - May 2012 - Load when idl on stable

Hi

I already post a message about my problem

I've three PC, all are Dell. Two laptop and one desktop.

All run FreeBSD 9-Stable amd64

Since 1 or 2 months I notice the load is never drop down 0.8-0.9 event when
nothing running but only on those laptop. 

I update today my desktop to last csup src and everything is fine on the
desktop. 

On both laptop the load is still at 0.8 - 0.9

And in same time the usb mouse on the laptop stop working meaning I can
use the touchpad, but if I plug a usb mouse, the kernel see the device but
the mouse not working on xorg.

Is' not block my work so I can live with that. I just want report those
problems.

Regards.

JAS

Is this due to a high rate of interrupts ?
i.e. can you see this with "systat -vm 1" with a large number in the
"intr"
field.

If yes, run "vmstat -i" to see what interrupt is being hit.

Then tell us what hardware is on that irq (from grep irq
/var/run/dmesg.boot).
