After the reboot everything was fine, but some time later INIT
segfaulted and said (from memory)
INIT: SEGFAULT: sleeping for 30 seconds.
That was reapeated a lot of times and I could neigther reboot, halt
nor switch runlevels.
I unmounted as many drives as possible (several processes couldn`t be
killed) and powered down.
Now its running again without any problems so far.
May the Source be with you.
