Everytime I run "make buildworld", I get the same lines and find myself
in the debug-prompt.

Here is my uname -a:
FreeBSD baustelle.otfa.local 5.3-BETA3 FreeBSD 5.3-BETA3 #0: Sun Sep  5

root at baustelle.otfa.local:/usr/obj/usr/src/sys/GENERIC  i386

And here are the last lines of output:

I used an unmodified 5.2.1-p9 GENERIC-System and upgraded it without
errors. The sources are from about 11:30 today (Sunday 05.09.2004).
