Hello,

after kernel has booted , when  shell is being
execve'ed it repeatedly loops in do_page_fault()
with address 0x0fc01788.

address 0x0fc01788 is well within user address space.

In do_page_fault() code

1.vma = find_vma(mm,address) goes succefully ..means address pertains to the current task.

2.but fails in
      if(!(vma->vm_flags & VM_GROWSDOWN)
         {
           goto bad_area;
         }

VM_GROWSDOWN flag indicates the stack area.

is this indicates problem with mmu initialisation..?

Best Regards,
