Hi all,
I have boot problem in my Gentoo iBook G3-800 with ReisrFS (if root partition have type ext3 all right)
root # cat /etc/fstab
/dev/hda3 none swap sw 0 0
/dev/hda4 /boot ext3 noauto,noatime,nodiratime 1 1
/dev/hda5 / reiserfs noatime,nodiratime 0 0
root #mac-fdisk -l /dev/hda
# type name length base ( size ) system
dump: name /dev/hda len 8
/dev/hda1 Apple_partition_map Apple 63 @ 1 ( 31.5k) Partition map
/dev/hda2 Apple_Bootstrap bootstrap 1600 @ 64 (800.0k) NewWorld bootblock
/dev/hda3 Apple_UNIX_SVR2 swap 1048576 @ 1664 (512.0M) Linux swap
/dev/hda4 Apple_UNIX_SVR2 boot 204800 @ 1050240 (100.0M) Linux native
/dev/hda5 Apple_UNIX_SVR2 root 57350080 @ 1255040 ( 27.3G) Linux native
Block size=512, Number of Blocks=58605120
DeviceType=0x0, DeviceId=0x0
root#
root#cat /etc/yaboot.conf
boot=/dev/hda2
device=hd:
partition=4
delay=3
timeout=3
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot
fgcolor=white

kernel:
VFS: Cannot open root device "hda5" or hda5
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on hda5

| Does your kernel have ReiserFS support built-in ? I think you need to have it builtin, and not as a kernel module. |

Allthough i think it doesn't really matter, but in your fstab, the numbers at the end of each line should be:
| Code: | /dev/hda3... 0 0
/dev/hda4... 1 2
/dev/hda5... 0 1 |
In any case, i have more or less the same config and never had any problem with it. Hmm... i wonder why you have the /boot-partition? Normally it's used to put your kernels and System.maps there, but your kernel is in /vmlinux. In any case, if you use /boot, you should manually mount it before running ybin. Hmm... did you try to mount the root partition with the livecd to see whether you can mount it as reiserfs and see whether everything is fine with it?
You could do that with something like this:
| Code: | mkdir /mnt/test
mount -t reiserfs /dev/hda5 /mnt/test |

in livecd mount -t reiserfs /dev/hda5 /mnt/test ok
vmlinux and System.map to be on /dev/hda4 |

You say that ext3 works.. did you test that with the exact same kernel? Which kernel are you running? Did you run "ybin -v" after building the new kernel?
If not, would you mind posting your kernel config? Or can i access it somewhere online? |

Did you get it to work in the meantime ?
The only thing i could find in your .config is that you enabled the pre-emptive kernel, which is not stable yet on ppc, but that shouldn't be the reason for the problem.
What i would do: compile the kernel again, copy system.map and vmlinux to the right place, check /etc/yaboot.conf again, run mkofboot, run ybin. And then hope it'll work. I can't see anything that looks wrong... |

Not sure whether you meant to do this or not, but a /boot partition really isn't needed for PPC systems. Folder, yes - partition, no. It might work anyway, but I've never pulled it off successfully. Try commenting out the /boot entry in your /etc/fstab, and moving the contents of the partition to the /boot directory on your root partition.
