6.5.0-T338 load question

I recently upgraded my Pro Pioneer to the latest 6.5 beta, and I have notice the system idles at a load of 1.

This is odd for two reasons, one is that under 4.2.x (and 6.4.2 on my ultra 4) the load has always negligible, and two, the load isn't attributable to any process running.

Now I have upgraded the CPU to a Q6600 so that maybe an issue, but I'm wondering if this is normal. My cpu has been running hotter than it did under 4.2, but I think that is because the fans are running much cooler than they did so I'm assumitg it would run cooler if I set the fan speed to cool.

I don't think I can do more troubleshooting without installing something like perf, but I don't want to push installing too much new software on the box. I'm assuming this is like the old readynas systems where you are generally OK install software as long as you don't overwrite the readynas specific packages.

Any insight would be appreciated, and great work on OS6 support on Legacy. The end result is very impressive!
