Subject: linux-v3.5-rc1: start of a user mode linux produces a core file

Whenever I start an UML image, I get a core file (nevertheless the UML
starts up fine).

The gdb back trace is :


Core was generated by `/usr/local/bin/linux-v3.5-rc1 earlyprintk
ubda=/home/tfoerste/virtual/uml/gento'.
Program terminated with signal 11, Segmentation fault.

(gdb) bt

v3.4 works fine, output of
$> /usr/local/bin/linux-v3.5-rc1 --showconfig > uml.config
is attached.
