Linux Kernel 2.6 on Artesyn Katana Board (3750) with IBM 750FX PP C

[Goel, Mudit (Mudit)]

All , 
  We have Artesyn Katana Boards with ppc boot version 1.2.0 (with different
release dates ).We have MV Linux  to be 
  used on these cards. 
  
  We are trying to upgrade the kernel to 2.6. The kernel upgrade is success
on one card with ppc boot version 1.2 
  with release date of July 2004. 
  
  But all other cards which have different dates but same boot version the
kernel upgrade is not successful.
  Here is the boot output
