Dear all,

I have installed Ubuntu 8.10 following the instructions from NAS central. I also re-compiled the Kernel. Everything was working fine.

However, I would prefer to use Debian instead. Therefore I formated the root drive and tried to install Debian with debootstrap using a two staged install for Powerpc. Unfortunately this does not work. I now get the following error:

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,6)

I also re-freshed the kernel image on the bootdrive and in flash-memory without success. I assume that this is an error of the initramfs but I do not know how to fix it.

Can anyone help me?

Regards,
Alex

Couple of things to check, sorry if they are obvious - are you pointing to the right root volume? Is the filesystem for the root volume built into the kernel?

Hi Timtim,

Yes, build it into the kernel and also tried with ext2 and jfs. As I said, it was working with the Ubuntu image. What modifications have been done to the Ubuntu image that I would also need to do to the debootstrap Debian system?

Regards,
Alex

I'm not sure why this doesn't work for you if its the same config for the kernel! In the case of the ubuntu image, I used the kernel I think i left it in the image with the config, and updated fstab, then deleted ssh keys, logs, histories etc so as to clean the image. The fan stuff might be in there too.
