X86_FS mode, atomic cpu.
Originally I actually was just using a vanilla ubuntu install and
upstart was aborting half-way and dropping me down to a maintenance
terminal. This actually is fine, but it wasn't mounting my swap space.
I then went through the ARM guide and removed a lot of the upstart
scripts. I didn't touch the tty's though and I didn't add the
modules.dep part seeing as im not really using any IO
I guess I could just mount the swap manually, but I don't really know
what else might be broken so it just seems safer to use a fully working
system...

As for why im not using the gentoo image, I need to install my own
software and I'm much more familiar with debian/ubuntu than gentoo
If you have an ubuntu image or a debian image that would be great! Where
can I find it?
Thanks,

Which ISA and CPU model are you trying to boot?
There is an extensive step-by-step document on how to setup Ubuntu for
an ARM system at
http://m5sim.org/Ubuntu_Disk_Image_for_ARM_Full_System.
It should be generally applicable for other ISAs one would think. My
experience with ARM Ubuntu FS, even with the Atomic CPU, it can take
about 30 minutes for Upstart to fully churn through and get to a geTTy
terminal prompt.

I'm trying to set up a custom ubuntu image to work with gem5. I got the
image to load into gem5 and the OS set up, but upstart seems to choke during
startup. I get to:
NET: Registered protocol family 10
IPv6 over IPv4 tunneling driver
NET: Registered protocol family 17
VFS: Mounted root (ext2 filesystem).
Freeing unused kernel memory: 232k freed
mount: proc already mounted
And then it wont progress past that point. Has anyone successfully got an
ubuntu image working?
Thanks,
Adam
