Describe the bug
With current master, I'm seeing > 96% CPU load on FMUv4 (pixracer), leading to log dropouts etc.

It seems that the load is high on boot, and then drops to around ~80% after a few seconds, and increases back to 95% when arming.

Tested with 270e12a

I have not yet found the time to check other FMUs.

To Reproduce
Just flash a pixracer and arm it.

Should be resolved, although there's plenty of room for further improvement.
