But .34 doesn't show this issue?

If so, can you run 'git bisect' between the .34 and .35 releases to find
out where the problem comes in?

Loadaverage can be affected by a driver doing an uninteruptable sleep.
This doesn't actually cause a load on the system, but it does affect the
way that number is calcuated.  Perhaps that's the problem here.

'man git-bisect' will help with this :)
