This was done as 'large' kernels couldn't be loaded as the RMA was too fragmented. Moveing it down to 1MB reclaimed just enough that we were fine. I assume that the yaboot-mainline and 1.3.17-4 tests we made with the same kernel/intrd combination. Can you get me a dump of your RMA memory properties and sizes of the kernel and initrd? I'd say that as most 'new' platforms have moved away from yaboot to grub we're probably safe to apply this but I'd like to do more digging before I commit to that. Yours Tony.
