FAILURE: Kernel module "calibrationTest" not installed. Check your SSH configuration
make[1]: *** [/somewhere/thomas/introot/rtai/calibrationTest.o] Error 1

The reason for this behaviour is/may be the an NFS mounted directory which hosts your $INTROOT. In the installation step, an error arises which complains about that no files can be created/installed. Normally root is not allowed to change/modify permissions on a network file system and root permissions are essential for ACS to install any kernel modules in lib/modules/`uname -r`/alma. So, the installation process stops here and things are only halfway installed. The resolution is simple:

1. move your $INTROOT to a local directory and the problems are gone or
2. Change the relevant configuration file on the NFS server so that root privilidges on the NFS clients are accepted by the server.
