Hi,

current tree (HEAD on 39710479303fd3a) gives quite non-informative and
confusing output during bootup:

The first part (the early reservations themselves with the names) are
fine, but the numbers that follow without any other explanation seem to be
just completely useless to me ...

I haven't yet looked at which code actually introduced this, but I guess
we should just remove it ... ?

Thanks,
