 Posted: Sun Nov 26, 2006 8:17 pm Post subject: unable to mount root & no valid partition |
 |
|
hi there, i have a strange issue on a PPC Tibook.
when i make a new kernel using the original and working .config and omitting alsa support, only after compill. and setting yaboot conf and ybin the kernel can not mount the root fs.
If i ask fdisk to -l, it says
| Quote: | | Disk /dev/hda doesn't contain a valid partition table |
The system is however up an running.
This system was originally put on a different parition and then copied to its present place.
Is it a yaboot issue? ??

Hi,
Are the correct partition types built into the kernel?
I got caught when shifting my root partition form ext3 to reisrfs and forgot that reiserfs support was complied as a module  |

Well, even if hfs is in-kernel, the problem is the same.
Should i reformat Blessed Partition and reinstall Yaboot?
Any advise?

fdisk will only display pc partitions, mac-fdisk is the tool that you should use to view Apple partitions.
As for ybin, post the output of mac-fdisk -l and the contents of your yaboot.conf.

yaboot.conf is this>
boot=/dev/hda2
device=/pci@f2000000/mac-io@17/ata-4@1f000/disk@0:
timeout=100
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot

image=/boot/vmlinux
label=g1
partition=3
root=/dev/hda3
read-only
image=/boot/vmlinux
label=gentoo
partition=6
root=/dev/hda6
read-only
image=/boot/vmlinux-new
label=new
partition=3
root=/dev/hda3
read-only
[/quote]
The ext3 fs, ApplePartitioning scheme and hfs support are in kernel, as well Macintosh partition map support. nfs root is not allowed.

What's the exact error? Perhaps you didn't start with make pmac32_defconfig and forgot to enable disk support?

pmac32_defconfig sounds alien to me - U might be right. Correction how?
Disk support is enabled - if U mean kernel support, that i know i have it enabled.
Thanx a lot.

From your kernel source directory, type make pmac32_defconfig. This will generate a default config for most Macintosh machines and should get you booting at least. If you didn't do this before configuring your kernel, the basic config is very sparse and people tend to forget to turn things on. :p

OK. Just one question.
In /usr/src there is a linux folder and the kernel i try to configure (2.6.19) , and a 2.6.17-r8 kernel in use. From which directory should i give this command?
