 Setup:
 =====

 RTEMS 4.11 (git -> master)

 Configure: /home/heandr/Projects/FEHLER/workingset/fame-
 dev/trunk/rtems/configure --target=arm-softfloat-rtems4.11
 --prefix=/home/heandr/Projects/FEHLER-work/fame-dev-tk71/install/arm-

 tk71 --disable-multiprocessing --enable-networking

 => ARM926
 => TK71-Board (Marvell Kirkwood)

 Application: a simple shell application

 system.h:

 ^^^^ END ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

 Remarks:
 ========

 I simply start a shell within the Init task without usage of the CBS
 scheduler. This renders the shell as a background task.

Comment:

 Gedare.. is this still an issue? Does it need work still? Was the patch
 OK?
