Hi everyone!
I had the kernel 2.4.26-gentoo-r6. I have solved to move to kernel 2.6.9
Did as it is written here - http://www.gentoo.org/doc/en/migration-to-2.6.xml. Kernel it was compiled orderly, in grub.conf has prescribed such parameters:
default 0
timeout 10
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
title=Gentoo-2.6.9-r6
root(hd0,0)
kernel (hd0,0)/boot/kernel-2.6.9-gentoo-r6 root=/dev/ram0 real_root=/dev/hda3 init=/linuxrc
initrd (hd0,0)/boot/initrd-2.6.9-gentoo-r6
But such message is given when loading:
>> Determining root device...
>>Block device /dev/hda3 is not a valid root device...
>>The root block device is unspecified or not detected.
Please specify a device to boot, or "shell" for a shell...
boot() ::
Wanted is loaded with old kernel, it was loaded, but ceased loads network interfaces, writes that not device is found /dev/eth0
Advise, is honoured it is necessary to do.
Is it Beforehand thanked for answer. |

Try to replace that line with | Code: | | kernel (hd0,0)/boot/kernel-2.6.9-gentoo-r6 root=/dev/hda3 |
and see what happens
[EDIT] Removed the '/linuxrc' part

Well, has done. Now gives such message:
VFS: Mounted root (ext2 filesystem) - (this beside me boot section /dev/hda1)
Mounted devfs on /dev
/linuxrc has to be run as the init process as the one with a PID of 1. Try adding init="/linuxrc" to the kernel command line or running "exec /linuxrc".
VFS: Cannot open root device "hda3" (this beside me root section /dev/hda3, type reiserfs) or unknown-block(3,3)
Please append a correct "root=" boot option
Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(3,3)
That will advise to do?

When I take a closer look at your grub.conf, I realized you try to specify, for example, "kernel (hd0,0)/boot/kernel-...". If you have the /boot in another partition, you don't need to specify the directory. So you should have only "kernel (hd0,0)/kernel-..." (without the /boot part). In grub you can use autocomplete. When you get the grub menu, type 'E'dit and delete the last part of your "kernel" specification. It's easy, just like bash autocompletion. You'll figure it out.
Also, you still have /devfs compiled in your kernel. I'd advise you recompile your kernel without devfs support. As long as I understand, you want udev instead of devfs (which is a good thing).
Please be aware of the fact that you have to compile reiserfs support IN the kernel, not as a module (or worse, not at all).
So, you have to do 3 things:
1) add support for reiserfs (if it's not already there);
2) remove devfs support (you have udev);
3) use grub's autocomplete to figure out the correct paths.
Please keep us informed.
Good luck!

I have vamoosed support devfs from kernel

But here begins interesting. In an effort do autocomplete is given report on mistake: Error 11: Unrecognized device string. It Was Loaded with old kernel and has checked, there is device hda. The Device there is.
In an effort is loaded with this new kernel are given former reports on mistake.
That will advise to do now? |

When I take a closer look at your grub.conf, I realized you try to specify, for example, "kernel (hd0,0)/boot/kernel-...". If you have the /boot in another partition, you don't need to specify the directory. So you should have only "kernel (hd0,0)/kernel-..." (without the /boot part). |
Have you done this part?

Yes. Result such - or Kernel panic (when root (hd0,0)/kernel-2.6.9-gentoo-r6 root=/dev/hda3) or report on that that Block device /dev/hda3 is not a valid root device ... Please specify a device to boot, or "shell" for a shell (when root (hd0,0)/kernel-2.6.9-gentoo-r6 root=/dev/ram0 real_root=/dev/hda3) |

Apologize, mistaken. The Correct variant:
/dev/hda1 /boot ext2 noauto,noatime 1 1
/dev/hda3 / reiserfs noatime 0 0
/dev/hda4 /usr reiserfs noatime 0 0
/dev/hda2 none swap sw 0 0
proc /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0 |

Well, maybe another silly question: have you really emerged udev?

Can I restore the system with LiveCD that program, which I have remained (not to install whole system, but kernel only)?
If yes, that as? |
