I do not think so. However, I have no idea what the problem could be.
Are you sure that you ran wait on the given pid? In order to be sure,
you can try and send SIGCHLD to the process father?
What would be really interesting too, is to have the process status. So,
in function sched_show_task, file kernel/sched.c, could you try and
print p->state in hexadecimal? In the dump you sent, the state is shown
as a question mark, so we do not really know in what state the task is.
You should also recompile your kernel with frame pointers, if it is not
already the case.
