I'm new to Gentoo on PPC, but I'm not new to Gentoo. I'm working on my first PPC install (G3 700mhz iBook), and am having a strange problem mounting the HD on boot. (Init scripts start to load, but mounting the root partition fails, complaining about a bad superblock.)

Is kernel 2.6.9 stable for G3 iBooks? It sounds like 2.6.9 was a step back for some Apple PPC users. Any advice for the best kernel to get started with? If anyone could contribute a known working (and maybe well tuned) Kernel config file, it could really help me out with troubleshooting the problem.

The init scripts are on the root partition... unless you are talking about scripts on a initrd.

Make sure that you specify the correct root partition and that your kernel has built-in support for the file system type used for your /.

I have 2.6.9 on the same laptop and no problem. Will send my .config tomorrow if you want.

Yeah, I'd love to see your config.

I'm using ext3, and I'm sure it's compiled into the kernel.

The init scripts (on the root partition) start to load just fine (Green gentoo [OK]s and all that). It freaks out when attempting to check fsck and all that.

I've googled my arse off, but I'm not turning up many results. Honestly, though... Troubleshooting can be fun sometimes. :D

Hi,

Ok. The kernel is able to mount it and has support for it but then it goes wrong after.

I would check the /etc/fstab
Make sure the fs types and options are ok.

Boot process is:
1) kernel mount root read-only (by trial and error for the fs type)
2) fsck checks / (probably using fstab for info)
3) init scripts remount read-write (using info from fstab)
4) ...

You can check/fix the fstab by booting single user mode:
linux init=/bin/bash
mount -t ext3 -o rw,remount /
nano /etc/fstab
(or other editor)

Here is my config:
http://www.sable.mcgill.ca/~dbelan2/config/config-2.6.9-gentoo-r2
for a reference. Though, I doubt that the kernel config has something to do with this specific problem.

Do you have devfsd on you disk?
Code:
$ ls /sbin/devfsd
ls: /sbin/devfsd: No such file or directory

then
Code:
emerge devfsd

I had this problem on stage3 @ 2004.3 .
