Actually kernel threads can dynamically change to a different kstack and allocate themselves a bigger one.. I forget where it is used but I remember that htere is codde in exit to clean up teh extra kernel stack if it is being used.. Is this running as a kernel thread or on a user's kernel thread stack?
