Can't tell whether my upgraded kernel is being booted

English Install/Boot/Login
#1

Hi all,

I just installed kernel version 2.6.26-rc2.5.1, but “uname -r” is still giving me 2.6.36-rc2-5-default. Am I booting with the new kernel? How can I tell? If not, how do I create a new boot option?

Thanks!

How exactly did you “install” it??

#3

Using Yast; it was in the “upgradeable” section.

#4

what do you see when you type:
ls /boot
?

#5

2.6.26- would be a downgrade from 2.6.36

#6

Whoops, that was a typo. Should read 2.6.36rc-2.5.1.

#7

And what’s the output of cat /boot/grub/menu.lst ?

#8

linux-gh8b:/home/kenny # cat /boot/grub/menu.lst

And you can check it in Yast also look at the version tab and see what it says is installed.

#10

Not sure where the version tab is, but under “kernel-default” in Yast, it says 2.6.36rc2.5.1.

#11

Provided such files exist on your system: /boot/vmlinux-2.6.36-rc-2.5.1-desktop.gz and /boot/initrd-2.6.36-rc.2.5.1-desktop , you can just add a similar entry in /boot/grub/menu.lst :

###Don’t change this comment - YaST2 identifier: Original name: linux###
title openSUSE 11.3 - 2.6.36-rc2-5.1
root (hd0,0)
kernel /boot/vmlinuz-2.6.36-rc2-5.1-desktop root=/dev/disk/by-id/ata-TOSHIBA_MK3265GSXV_50V5S1HOS-part1 resume=/dev/disk/by-id/ata-TOSHIBA_MK3265GSXV_50V5S1HOS-part2 splash=silent quiet showopts acpi=noirq vga=0x317
initrd /boot/initrd-2.6.36-rc2-5.1-desktop

Of course the filenames have to match exactly the ones in /boot/

#12

Okay, those files don’t exist in /boot, and the file list for kernel-default (which says version 2.3.36rc2.5.1) in Yast says “System.map-2.6.36-rc2-5-default, config-2.6.36-rc2-5-default, initrd, initrd-2.6.36-rc2-5-default, initrd-2.6.36-rc2-5-kdump, symvers-2.6.36-rc2-5-default.gz, vmlinux-2.6.36-rc2-5-default.gz, vmlinuz, vmlinuz-2.6.36-rc2-5-default”, none of which have the “.1”.

I guess maybe I just don’t understand how the upgrade works. Maybe some of the other files were changed?

#13

you can see the date/time of these files with:
ls -la /boot
So you will see if they are new or not.

You are probably using gnome if you can’t see it.

Ok, fire up the software manager, click the “installed” button, top right. Write “kernel” in the
search box. Click on “kernel-default” in the list below. Then, in the right-bottom corner you will
see a label for “installed” and another for “available”.

Post here what you see under both labels.

Under the “available” label there is a drop list that allows you to select the same or a different
version - depending on what you choose, the button below will read reinstall, downgrade, or upgrade.

Or, you can fire the kde version of yast instead. Type alt-f2, and type “gnomesu - -c /sbin/yast2
–qt sw_single”. Press enter, give root password. Wait.

In the search box, type “kernel”. Click once in the list, entry "kernel-desktop. In the box below
there are several tabs, and one is labeled “versions”. One will have a check mark, another a filled
circle, and several empty circles.

Report what you see.

If what you see is different, make a photo and upload it somewhere (picpaste, f.e), so that we can
see it.
