we have Artesyn Katana Boards with ppc boot version 1.2.0 (with
different release dates ).We have MV Linux CGE4.1 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 and release date of July
2004. But all other cards which have different dates
but same boot version the kernel upgrade is not successful.

Any pointers would be appreciated
