I try to use NFS in l4linux and have problem. This happens on ARM and on X86:

This warn message should only come when there's a page-fault outside of the user accessible VM area, but bfdfeb40 is actually in there. So I wonder why this happens and what the value of TASK_SIZE is. Could you add this to the printk? (in arch/l4/kernel/dispatch.c).
