I installed the basic 5.02a Debian system with just a minimal install then I installed the 2.6.26-2-686-bigmem kernel so it will see all the memory. When I boot into the bigmem kernel it fails to boot, the errors I get are: WARNING boot device may be renamed. Try root=/dev/hda3 ... ALERT! /dev/sda3 does not exist Did you try with changing the root device for the bigmem kernel to /dev/hda3? If you use grub for booting you could do that by pressing 'e' (for edit on the line with the bigmem kernel) and afterwards pressing 'b' (for boot) while in the grub menu (to just try it) or updating /boot/grub/menu.lst (for the bigmem kernel) and running update-grub before rebooting into the bigmem kernel. Thanks for your response, I did try what you suggested but got the same error, except it says that "/dev/hda3 does not exist". Looking in /dev there is no sda* or hda*, there only an hda which I think is the CD drive. When I boot to the default Kernel then /dev/sda3 exists and is used to boot the kernel. Any other ideas?Does this system use the aacraid driver? If so, please try testing the kernel from lenny-proposed-updates (2.6.26-19).
I'm not sure if this server is using this driver. However, we have resolved this issue. It turns out that we needed to upgraded the firmware on the Raid controller to get it to work. After the upgrade it boot fine and I can see all the memory.
Thanks for the help,
