Kernel Upgrade (Solved!!)

[snakeo2]

Im going to be upgrading to the latest stable kernel and I since the last time i went through a kernel upgrade was such a bad experience, I figured I post my plan of action in order to get expert advise as to anything I may be missing...etc.

first my current information:

ls -l /usr/src/linux
lrwxrwxrwx 1 root root 22 Jun 6 2007 /usr/src/linux -> linux-2.6.20-gentoo-r8

my fstab file

# /etc/fstab: static file system information.
#
# noatime turns off atimes for increased performance (atimes normally aren't
# needed; notail increases performance of ReiserFS (at the expense of storage
# efficiency). It's safe to drop the noatime options if you want and to
# switch between notail / tail freely.
#
# The root filesystem should have a pass number of either 0 or 1.
# All other filesystems should have a pass number of 0 or greater than 1.
#
# See the manpage fstab(5) for more information.
#

# <fs> <mountpoint> <type> <opts> <dump/p$

# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/sda1 /boot ext2 noauto,noatime 1 2
/dev/sda3 / ext3 noatime 0 1
/dev/sda2 none swap sw 0 0
/dev/sda5 /home ext3 noatime 0 1
/dev/hda /mnt/cdrom iso9660 noauto,ro 0 0
/dev/hdb /mnt/dvd iso9660 noauto,ro 0 0
/dev/fd0 /mnt/floppy auto noauto 0 0

# NOTE: The next line is critical for boot!
proc /proc proc defaults 0 0

glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
# POSIX shared memory (shm_open, shm_unlink).
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will
# use almost no memory if not populated with files)
shm /dev/shm tmpfs nodev,nosuid,noexec $

my system profile:

ls -FGg /etc/make.profile
lrwxrwxrwx 1 59 Nov 22 18:23 /etc/make.profile -> ..//usr/portage/profiles/default/linux/amd64/2008.0/desktop/

eselect kernel list
Available kernel symlink targets:
[1] linux-2.6.17-gentoo-r4
[2] linux-2.6.20-gentoo-r8 *
[3] linux-2.6.24-gentoo-r8
[4] linux-2.6.25-gentoo-r7
[5] linux-2.6.26-gentoo-r3

My plan is to compile kernel 2.6.26-gentoo-r3. If I'm not mistaken I will have to mount my /boot partition once I'm done compiling kernel-2.6.26-gentoo-r3 and copy the bzImage to /boot partition. Also, whatever name I give it, I will then have to create an entry with the exact name on my grub.conf file. The main issues I had the last time around was due to a driver for my sata drive and my box would not boot as a result of it. I'm assuming that this time around it will take my existing config file and build on it the latest capabilities of the latest kernel. I wanted to take a look at my config file to write down the driver for my sata drive just in case and I came across the following error:


make menuconfig
make: *** No rule to make target `menuconfig'. Stop.

any ideas what is causing this? thanks in advance.

where did you run make menuconfig?
you have to be in /usr/src/linuxXXX.
i have this in my grub.conf

[NeddySeagoon]

snakeo2,

Your method is about right but its lacking in detail about how you will configure you new kernel.
you can copy your .config file but its not suitable for the new kernel as it stands.
Some things that were in 2.6.20 have been dropped and new things have been added to make 2.6.26

After you have copied over your .config file you must run make oldconfig in the new kernel tree.
This silently drops options that are not in 2.6.26, uses the existing settings for things that have not changed and asks you questions for all the new options. You will get a lot of questions.

When thats done, look over your settings in make menuconfig. Migration is easier if you do it more often. You can still do that as you can build and test all the indermediate kernels you have.

NeddySeagoon,

Not sure if you remember, but it was your help that finally got me to boot into my system the last time around. You helped me extensively by looking over my old config file and creating a new custom config file that allowed me to boot back into my system. In your opinion, what would be the easiest way to proceed? Thanks in advance.

@NeddySeagoon: you are right, i forgot to mention copying .config and make oldconfig.
@snakeo2: something went wrong with your sources directory.
unfortunately it is not clear where your linux symlink points to.
anyway, as NeddySeagoon already described, copy your .config to the directory of the kernel version you want to build.
if this error happens on the the kernel you are planing to build, then you will have to re-emerge these sources.

[snakeo2]

Alex,

If I understand it correctly, I need to do the following:

cd /usr/src/linux-2.6.9-gentoo-r2
# cp ../linux-2.6.9-gentoo-r1/.config .
# make oldconfig

except that in my case it would be more like so:

cd /usr/src/linux-2.6.26-gentoo-r3
cp ../linux-2.6.20-gentoo-r8/.config
make oldconfig

i don't want to make any guarantees, but that looks fine.
what exactly was the problem the last time?
remember, you can access your former kernel from the grub menu when configured correctly.

[snakeo2]

thanks for looking over my settings. As Neddy pointed out during my last kernel migration,

You have both
Code:
Support for SATA (deprecated; conflicts with libata SATA driver) (BLK_DEV_IDE_SATA)
which makes your SATA devices appear as /dev/hd... and
Code:
Serial ATA (prod) and Parallel ATA (experimental) drivers
which is the new SATA driver support in your kernel. You must not have both. In effect you have two drivers for the same piece of hardware, as is normal in that situation neither works properly.

Turn off
Code:
Support for SATA (deprecated; conflicts with libata SATA driver)

this was the problem and I couldnt boot. Thanks to Neddy, I was able to get back into my system. I will go ahead with the kernel migration and post back any errors, thanks once again.

ok, i went ahead with the kernel upgrade and thought everything went fine until i tried to reboot of course. when i reboot, im getting the "error 15: file not found" message. i know this mean that there is something wrong with my grub.conf file, but not i do not know what exactly. i can login to my previous kernel, but i have no GUI as something is wrong with my xorg. anyways, here is the exatc error i get:

root (hd1,0)
Filesystem type is ext2fs, partition type 0x83
kernel /boot/2.6.26-gentoo-r3 root=/dev/sda3

error 15: file not found

press any key to continue...


im guessing i screwed up when i did cp arch/86_64/boot/bzImage...etc

i will post back with my grub.conf file

here is the grub.conf entry i created for the new kernel i just compiled:

title=Gentoo-Server-2.6.26
root (hd1,0)
kernel /boot/2.6.26-gentoo-r3 root=/dev/sda3'


im little confused,


should i do " cp/arch/x86_64

a) cp arch/x86_64/boot/bzImage /boot/kernel-2.6.26-gentoo-r3

b) cp arch/x86_64/boot/bzImage /boot/2.6.26-gentoo-r3

c) cp arch/x86_64/boot/bzImage /boot/Gentoo-Server-2.6.26-gentoo-r3??????


thanks in advance

snakeo2,

Error 15 from grub means that a file you have asked it to load cannot be found
Your splashimage should not have changed and you don't use an initrd file, so it can only be the kernel.

You should have added a booting stanza to grub.conf to boot your new kernel, so you can also choose the old one.
We all make a kernel that won't boot from time to time.
The booting stanza is the bit like:-

[snakeo2]

neddyseagoon,

im pretty sure that the /boot partiton was mounted.

i did exactly what you suggested. I looked at the entry in grub for the kernel that was working and only chaged the title and the kernel /boot name. here is what i have in my grub.conf for the old kernel and the new one that im trying to get to boot:


old kernel:

title=Gentoo Server Manual
root (hd1,0)
kernel /boot/2.6.20-gentoo-r8-manual root=/dev/sda3


new kernel

title=Gentoo-Server-2.6.26
root (hd1,0)
kernel /boot/2.6.26-gentoo-r3 root=/dev/sda3

i just did "cp arch/x86_64/boot/bzImage /boot/2.6.26-gentoo-r3" again to see if it works this time. i have mounted


ls -l /boot

-rw-r--r-- 1 root root 2999856 Nov 30 20:11 2.6.26-gentoo-r3 (new kernel)


rw-r--r-- 1 root root 2864983 March 11 2008 2.6.20-gentoo-r8-manual (old kernel)

[snakeo2]

just to clarify, the installation guide suggest that when you copy the bzImage to the /boot partition you do it like so:

cp arch/x86_64/boot/bzImage /boot/kernel/(kernel-name)....which is not how i did it. also, since i have a separate /boot partition when im copying the bzImage, should i do it as follows:

cp arch/x86_64/boot/bzImage /mnt/gentoo/boot/kernel/(kernel-name).....thanks in advance

[NeddySeagoon]

snakeo2,

The copy works of /boot is mounted or not. If /boot is mounted, the kernel goes where you expect and where grub will find it.
When /boot is not mounted, the kernel goes to the /boot directory on the root filesystem, where grub will not find it.

[snakeo2]

i just tried again and im getting the following error:

here is what i did:

cp arch/x86_64/boot/bzImage /boot/kernel/2.6.26-gentoo-r3

cp: cannot stat 'arch/x86_64/boot/bzImage': No such file or directory


df -T

sorry, but im typing from another computer so im only posting the line the refers to my /sda1 (boot partition)


Filesystem Type 1k-blocks Used Available Use% mounted

/dev/sda1 ext2 241116 14803 213865 7% /mnt/gentoo/boot


i already posted the output of "ls -l /boot"


thanks

Ok, I found an old livecd and I'm using it now which should make copying and pasting much easier. I think i found the problem:

I went ahead and chrooted into my box, not sure if it was needed. Navigated to my /boot partition

ls /boot
2.6.20-gentoo-r8-manual
System.map-genkernel-x86_64-2.6.17-gentoo-r4
System.map-genkernel-x86_64-2.6.20-gentoo-r8
boot
grub
initramfs-genkernel-x86_64-2.6.17-gentoo-r4
initramfs-genkernel-x86_64-2.6.20-gentoo-r8
kernel-genkernel-x86_64-2.6.17-gentoo-r4
kernel-genkernel-x86_64-2.6.20-gentoo-r8

as you can see there is no entry for "2.6.26-gentoo-r3"

which is odd, because before i tried to copy the bzImge to /boot, I made sure my /boot partition was mounted by issuing the following commands:

mount /dev/sda1 /mnt/gentoo/boot
then
cp arch/x86_64/boot/bzImage /boot/2.6.26-gentoo-r3

my question is how can i make sure the bzImage gets copied over to my /boot partition so that it shows...?

[jcat]

There is no magic to copying files, you either copied it to the correct location (/dev/sda1) or not (/dev/sda3), boot was either mounted of it wasn't.

What's you current status, have you managed to copy your kernel file in place and booted?



Cheers,
jcat

[NeddySeagoon]

snakeo2,

Get into your chroot, including mounting /boot and do the following

[snakeo2]

Happy to report that all is good now. I was able to copy the bzImage to the right place and I'm now back in business. Thanks to everyone for your tips and advise.
