can top be used to show everything?
Or is load at 1.94% ?!
[update] i just went back to SNAPSHOT, r3190-271db9f again and the load went back to
1 Minute Load: 0.33 Average: 0.33 Peak: 0.78
5 Minute Load: 0.24 Average: 0.24 Peak: 0.27
15 Minute Load: 0.10 Average: 0.10 Peak: 0.10

Load average has a lot to do with I/O.
There could also be a stat bug.

i think i found the culprit: kmod-ledtrig-netdev - 4.4.45-1
I was missing this kernel module and that flooded the logfile, that there were missing drivers for the LEDs in the router..
Once i installed it high cpu load seems to be gone.

quite some time ago.. the issue still comes up, but seems to be far less often since i removed all LED configurations.
furthermore the mwlwifi has one bug, that causes CPU load to go through the roof.
