Well, rebuilt World, kernel, installed kernel, rebooted into single
user mode, installed world, but still have the same problem. When going
from multi user mode to single user mode: the computer immediately exits
single user mode and boots into multi user mode. When starting the
system and booting into single user mode, this does not happen.

I'd appreciate your suggestions...
