I upgraded my system several times before,

are you saying that one is unable to run successfuly 'make installworld' until the new 
kernel is booted?

has anyone even try to look at the error?

Agreed, but in this context, I think we are talking about running the
disparate kernel and world, in either event, only as long as it takes to get
both parts, the new kernel and the new world, installed.  Surely, an old
world on a new kernel will have the exact same problems (or the exact
opposite problems?), in that newly-built programs such as ps and top may
have been altered to take account of new kernel memory structures etc, which
won't be available until the new kernel is installed and booted.

Anyone who is up to using buildworld should have enough understanding to
know that you have to build and install both parts for your system to work

But even then, there will be some disparity between the running kernel and
the running world, no?  This will only be resolved once all steps are
complete, whichever particular sequence of events you follow.
