May I ask why you are trying to communicate with L4 IPC instead of using
Linux primitives for the App<->Linux case? This sound strange at least.

When you say "the register values contains some 'random' values", do you
mean that the IPC syscall returns without error but the message words
contain values they're not supposed to contain?
