Hello Laurent,
that did the trick! Don't get dependencies checked at load time? I
mean undefined functions lead to load errors. I just want to learn to
be prepared next time. So was it some data structure that gets
properly initilized by iommu2 so that insmod cannot see the error?
Thanks for enlightenment,
Bastian
