Description

Manually stopping the start time, and looking at the output of the Dediprog EM100Pro, the start with serial console and 128 GB of RAM takes more than 60 seconds, showing that the times calculated by cbmem -c are off.

Nico suggested, that cbmem takes some value from the running system to scale them, which seems to be wrong.
