I was going to say I have no idea, but looking at it again ... this is in the *resume* code, not the suspend code as I'd assumed, and on resume I guess I felt it was safer to not assume it didn't change, since it could be a slightly different kernel that loaded and restored the hibernation image? It should be the same one, so I guess it should be exactly the same code, but I guess I wanted to make sure there wasn't anything weird there. As for why it'd be 32 MiB? No idea. Although that really ought to flush all your possible caches anyway, I guess. johannes _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
