 Posted: Sun Jul 02, 2006 10:56 am Post subject: Yaboot on G3 hangs "please wait loading kernel" [s |
 |
|
I have searched here, RTFM and yaboot does not find kernel [Edit finds kernel now but hangs scroll to 2nd post by turtles]. From rebooting the live cd I | Code: | livecd ~ #mount /dev/hdb4 /mnt/gentoo livecd ~ # mount -o bind /dev /mnt/gentoo/dev
livecd ~ # mount -o bind /sys /mnt/gentoo/sys
livecd ~ # chroot /mnt/gentoo /bin/bash
livecd / # /usr/sbin/env-update && source /etc/profile
>>> Regenerating /etc/ld.so.cache...
livecd / #nano -w /etc/yaboot.conf |
[EDIT out all comented lines to save space.]
| Code: | boot=/dev/hdb2
device=hd:2 #I also tried a 1 here and leaving blank like it shows in manual#
partition=4
delay=10
timeout=40
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot
image=/boot/2.6.16-gentoo-r9
label=Linux
root=/dev/hda4
partition=4
read-only
ofboot=hd:1
|
Question remains why wouldent yaboot find at least a broken kernel?? Me thinks it has to be | Code: | /boot/kernel-2.6.16-gentoo-r9
|
Instead of
| Code: | | /boot/2.6.16-gentoo-r9 |
and now i emerged mac-fdisk in the chroot so I dident have to keep re chrooting every time yabootconfig doesnt work.
| Code: | (chroot) livecd / # yabootconfig
yaboot is the Linux Loader for PowerPC. yabootconfig sets up your system to boot directly
from your hard disk, without the need for a boot CD, floppy or a network boot.

What do you mean by: "yaboot does not find kernel"? Is there a specific error? Everything looks fine to me, the boot link is a link to prevent people with seperate /boot partitions from screwing up their paths. Grub2 is not mature enough to suggest it for regular use.

Edited above post and title to better describe problem
UPDATE
I could do a on the live cd but not chrooted
From the chroot
I have tried adding a few different combinations to /etc/yaboot.conf
| Code: | device=hd:/pci@80000000/mac-io@10/ide@20000/disk@1:2
|
did not work
then
| Code: | | device=/pci@80000000/mac-io@10/ide@20000/disk@1:2 |
did not work
then
| Code: | | device=/pci@80000000/mac-io@10/ide@20000/disk@1: |
did not work
then
| Code: | | device=hd:/pci@80000000/mac-io@10/ide@20000/disk@1: |
| Code: | livecd / # mkofboot -v
mkofboot: Finding OpenFirmware device path to `/dev/hdb2'...
ofpath: Unable to determine sysfs mountpoint
mkofboot: Unable to find OpenFirmware path for boot=/dev/hdb2
mkofboot: Please add ofboot=<path> where <path> is the OpenFirmware path to /dev/hdb2 to /etc/yaboot.conf
|
thanks again for ANY ideas!

Part way to solved!
From the live cd (non chrooted)
then adding a line to /etc/yaboot.conf that contains the output of :
| Code: | #OpenFirmware device path
ofboot=/pci@80000000/mac-io@10/ide@20000/disk@1:
|
got me
| Code: | livecd / # mkofboot -v

But now it wont boot on reboot (does automaticly go to the cdrom after the grey ? / mac screen
UPDATE (at hour 5 of yaboot)
Ok so I removed the drive from the computer and set it up as hda and made shure it was set as a MASTER drive it had a jumper "cable select" installed wich I moved to master.
I changes fstab, and yaboot.conf
ran ybin and mkofboot again with no errors. ran yabootconf to check file and it compalins | Code: | ofpath: /dev/hdb: No such file or directory
yabootconfig: Unable to determine OpenFirmware device name to /dev/hdb, aborting... |
A quick doubble check and I have in fact changed all entrys to /hda from /hdb.
UPDATE
I reboot and get "Welcome to yaboot version 1.3.13
Enter "help" to get some basic usage information
boot:linux
please wait loading kernel....."
and it just hangs ther forever?
UPDATE
I finaly got yabootconfig to run without errors, and I have compiled 2 kernels so I am going back to the first one for this round. yabootconfig generates:
| Code: | GNU nano 1.3.9 File: /etc/yaboot.conf
## yaboot.conf generated by yabootconfig 1.0.8
##
## run: "man yaboot.conf" for details. Do not make changes until you have!!
##
## For a dual-boot menu, add one or more of:
## bsd=/dev/hdaX, macos=/dev/hdaY, macosx=/dev/hdaZ
boot=/dev/hda2
device=/pci@80000000/mac-io@10/ide@20000/disk@0:
partition=4
root=/dev/hda4
timeout=30
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot
image=/boot/2.6.16-gentoo-r9
label=Linux
read-only

MORE INFO:
| Code: | livecd / # ls /boot/
2.6.16-gentoo-r9 boot kernel-2.6.16-gentoo-r9
livecd / # nano -w /etc/yaboot.conf

I guess I should mention that the live CD has a coupple of errors on boot up one about a signel 11 and quite a few about ipv6, I made a 2nd live cd today and it has same errors, they are minor but you never know the errors are reported here kinda https://bugs.gentoo.org/show_bug.cgi?id=126688.
I reboot and it just hangs ther forever?
If it were a kernel problem wouldn't it say kernel panic???
I cant tell if it is related to this https://bugs.gentoo.org/show_bug.cgi?id=119642
Anything I missed?
UPDATE
Looks like there is a bug https://bugs.gentoo.org/show_bug.cgi?id=126421
This bug is resolved as a wont fix but does not accuratly match this problem. The bug report says | Quote: | | The work around is to use the "nodetect" option. |
I do not understand what that means or how to do/ try that. It is G3 imac 233 (REV B) blue and white. it has been running gentoo for a wile as a server and it does a great job i would like to keep it out of the trash for a wile longer.

Incase anyone is having the same problem JoseJX just pointed out that I hac /etcfstab configured wrong there is no line needed for apple bootstrap.
[url]gentoo.org/viewtopic-t-457922-highlight-ppc+fstab.html[/url]
We will try yabootconfig again after the update world finishes.

Assuming that the information you post is correct...
From your yaboot.config:
From the output of mac-fdisk:
| Code: | /dev/hdb4 Apple_UNIX_SVR2 root 155251248 @ 1050240 ( 74.0G) Linux native
|
So what IS the disk and partition where yaboot is supposed to load the kernel: hda4 or hdb4? |

Short answer = hda
To clarify & summary: - between the above posts I removed the drive from the computer to check for hard ware issues.
- Drive had a jumper "cable select" installed.
- I moved jumper to master.
- Drive showed as hda instead of hdb on reboot of live cd.
- I edited fstab, and yaboot.conf to reflect the hdb to hda change.
(the imac seems to support only 1 hd so the cable select was my mistake)
- ran ybin and mkofboot again with no errors.
- ran yabootconf to check file and it compalind
| Code: | | ofpath: /dev/hdb: No such file or directory |
I think was because I had not remounted properly? yabootconfig later ran with no errors.
I did not end up with the | Code: | #OpenFirmware device path
ofboot=/pci@80000000/mac-io@10/ide@20000/disk@1: |
in the new /etc/yaboot.config generated by yabootconfig. Upon reboot yaboot hangs at please wait loading kernel on 2 different kernels I compiled It was pointed out I had hda /boot in fstab, not needed so I removed and resaved fstab
the emerge --info /etc/fstab, mac-fdisk, /etc/yaboot.config and everything you ever wanted to know about the computer is[/list][/list] here.
to save space.
It has been so long that I am now up dating the system which is leading me to update gcc and recompile, getting errors with this so i wont be rebooting for a little wile.
Thanks for ANY ideas, soloutions, thoughts or just reading.

FAQ says | Quote: | | There is an 8GB limit for the root partition |
Looks like I'll be using parted to resize my root because mac-fdisk cant resize.
Since I am going to mainly be using it as a headless server for apache2 cups postgres database. would anyone have any recomendations on a partitioning lay out??? srever details here
thanks for any ideas!

|
then I used mac-fdisk to delete the root
| Code: | livecd ~ # mac-fdisk /dev/hda
/dev/hda
Command (? for help): d 4
|
And created a 8 GB root
| Code: | Command (? for help): c

Length (in blocks, kB (k), MB (M) or GB (G)): 8G
Name of partition: /root
|
I then created a /var 30GB
and a /usr (rest of disk)
And it now boots
But how does it know that I "moved" var or that I moved "usr"?
Thanks for the help.

I'm glad it boots now. In order to use those partitions, you must mount them (add them to fstab) when the computer starts. If you didn't do this already, it will put all of the files intended for /var and /usr on the root partition instead.
