I enabled IPC logging, but I'm not sure what should I see in the trace buffer.
It's always doing the same, that should not be.

So, I put my files in http://getgid.postech.ac.kr/l4.tar.gz.
With your files I can see this behaviour as well. It's not the kernel, at least. But I can't see any further what it really is. In dispatch.c there's a #if 0 at the beginning of the file. Make that to #if 1 to enable the logging macros and rebuild. (Your source tree is up to date, right?) Now I'd like to see the trace log right after init has been started. You should make that image available, maybe I can dig a bit further this way.
