Unless you have a new version of DINK that is fixed, it doesn't set up the memory controller correctly for the RAM above 32MB. There should be comments indicating this in arch/ppc/platforms/sandpoint_setup.c:sandpoint_find_end_of_memory() or some such (since I don't know what version of MVL you're running). Try it again with only this on your cmdline: "mem=32M" and see if that helps. Mark ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
