MontaVista 4.0.1, kernel 2.6.10. We recently had a need to increase memory. We
can populate 1x256M, 2x256M, 1x512M or 2X512M. In all configurations with at
least 512M, it we set memory size to 496M or greater system crashes on boot up while
populating rootfs. With memory size set to <496M system boots and runs fine.
U-boot can see and access/test all memory. </span></font></p>
