At a guess, I'd say that the SDRAM controller is not correctly configured, so you're getting memory aliases over the 256MB you've given the kernel. Try reducing the amount of memory by a factor of two and see whether that prevents the OOPS occuring. If so, it points to incorrect SDRAM configuration. ------------------------------------------------------------------- List admin: http://lists.arm.linux.org.uk/mailman/listinfo/linux-arm FAQ: http://www.arm.linux.org.uk/mailinglists/faq.php Etiquette: http://www.arm.linux.org.uk/mailinglists/etiquette.php
