I have successfully compiled L4, so that the examples work, and have got
my own little test user tasks to run as well. However, when I try to
run a slightly larger program as the roottask, I never even get to
launch the kernel. It dies with the message "Conflict with multiboot
module 0\nPlease choose a different link base." The full output is:

I have tried to work out how to solve this from the L4 source code, but
not succeeded. Could anyone please explain to me more exactly what the
problem is, and give some guidance to fixing it.
Many thanks,
Adam Antonik.
