I tried uisp as root as well, that change not the bahavior. You are
right that
I tested with strace with user rights. Sorry. But my root-strace
looks absoluly equal, only the uid (0) and the pid is an other.
After getpid it crashes. :-(

In the dump you can see no ioperm call. I think there is a problem with
but where and how to fix that?
