Help with Nios II linux from rocketboards.org

I've got a previous MMU design from the older uClinux-dist that I know works. I have a *.dts and my *.sof that I'm not trying to get going on the Rocketboards Nios II linux-socfpga.

I'm just downloading directly to RAM so I just goto Platform Options and select my *.dts and build the vmlinux kernel for downloading.

It runs on the DE2-115 Terasic board. I have a daughter card with a compact flash adapter. So in the kernel configuration I also enable SCSI disk support and Serial ATA Generic platform device PATA support.

When I do a "make vmImage" I get the following error:

****************************************************************************8

Can anyone help tell me what's the problem? Thanks in Advance

Oh - if I remove the SCSI I can't boot either -- I get:

Linux version 3.14.0-00598-g8adb74d (user1@localhost.localdomain) (gcc version 4.7.3 (Sourcery CodeBench Lite 2013.05-43) )# 7 Wed May 7 13:20:41 CDT 2014

bootconsole [early0] enabled

early_console initialized at 0xe9004040

BUG: failure at mm/bootmem.c:378/mark_bootmem()!

Kernel panic - not syncing: BUG!

Any help would be greatly appreciated.

I'm assuming that the Rocket boards Nios II linux is what I should use now for Altera nios2? If this isn't true then please let me know.

Also, is this all MMU or can I do a non-MMU project by just not having it in the *.dts file?
