Great! if you still have issues with the long mode, you could try to
hack gnumach to wait at some point (e.g. user_bootstrap() or
setup_main()), attach with gdb and then continue. Either with some delay
or polling a flag that you flip from gdb once attached. In this way you
should be able to set a breakpoint in userspace.
OK, but how do I actually get the task to start / run? :D
I can't debug it if it's not run...
did you add $(task-resume) in the boot script?
With that instead of the prompt-version I see

module 0: module-bootstrap-hello m1 ${host-port} ${device-port}
$(task-create) $(task-resume)
1 multiboot modules
task loaded: module-bootstrap-hello m1 1 2
