  Everything is ok upto here. Except that you need not load 'ls'. init=20
executes sh (a very simple shell) and from there you can execute through=20
command prompt.
 As the matter of fact, the project is still in the primitive stage and=20
contails zillions of bugs. :)=20

 >> get_page (); get_page used before memory initialization
 It seems there is some bug in vm/vmpage.c
I did not expected it to call get_page before that function (may be through=
=20
page fault).
Looks like a bug.
 How much memory do you have?
It seems you have >256 ... 512 perhaps. The page table entry is created for=
=20
Only first 4MB. You system required more than that for page_page.=20

What is the output that I should get? Do I need to get

  It seems the problem is with the code itself. give me time to have a=20
closer look.......
try on 128MB if possible.
