Can you post your dmesg output with 4 GB of RAM and also for 2 GB if possible? If you have your kernel patched to fix the issue, it would probably be best if you can revert to the non-patched kernel for the purposes of gathering this information. Also please post the info from /proc/iomem. If you did patch your kernel, can you post the patch you used?
