im using the directorys below and its still leading to a unbootable system can anyone help !?!?


after downloading the kernel - untar it with:

Code:
tar xf linux-kernel-2.6.23-rc7+tools.tar

then enter the linux-kernel... directory and install it:

Code:
cd linux-kernel-2.6.23-rc7+tools
sudo dpkg -i linux-headers-2.6.23-rc7-powerpc64-smp-custom_20070924_powerpc.deb
sudo dpkg -i linux-image-2.6.23-rc7-powerpc64-smp-custom_20070924_powerpc.deb
sudo dpkg -i ps3pf-utils_2.0-1_powerpc.deb
sudo dpkg -i wifi-radar_1.9.8-0ubuntu2_all.deb

______________
With beginning of kernel 2.6.22 the devices for the ps3 are natively supported. This means the hard drive is not longer used as a scsi device but we have a special device /dev/ps3da1. This means we have to edit kboot.conf again.

change the line

Code:

linux='/boot/vmlinux initrd=/boot/initrd.img root=/dev/sda1 quiet splash'

again, so that the we juse the new boot device:

Code:
linux='/boot/vmlinux initrd=/boot/initrd.img root=/dev/ps3da1 quiet splash'


Alternativly you can choose use the UUID of the boot device.
1. Look into /etc/fstab. Ubuntu alread mounts the partitions by UUID, so just copy the UUID from there.

find the line with your root partition (this is the one with / as mountpoint)

Code:
# /dev/sda1
UUID=ef6ece50-37d5-4b61-9bbf-fd5330b93354 / ext3 defaults,errors=remount-ro 0 1

On my Ubuntu it looks like this. In other configuration you would find in the first column /dev/sda1 instead of UUID=xxxx

2. now copy the complete UUID entry - means UUID=ef6ece50-37d5-4b61-9bbf-fd5330b93354

and edit your kboot.conf again:

change this line

Code:
linux='/boot/vmlinux initrd=/boot/initrd.img root=/dev/sda1 quiet splash video=ps3fb:mode:5'

so that it looks like this:

Code:
linux='/boot/vmlinux initrd=/boot/initrd.img root=UUID=ef6ece50-37d5-4b61-9bbf-fd5330b93354 quiet splash video=ps3fb:mode:5'

Make sure you insert the copied UUID from Step 1. alas you will insert my UUID  Which will lead to an unbootable system again.

You can now reboot to the new kernel. If something goes wrong, reboot with old kernel.
