I have the same problem with a newly install and updated Kubuntu Karmic
9.10 on a 64bit machine.
Issuing uname -a gives the following result:
Linux lagoon 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:05:01 UTC 2009
x86_64 GNU/Linux
However, I have the following kernels installed via the security updates:
[~]>dpkg -l | grep linux-image
ii linux-image-2.6.31-14-generic 2.6.31-14.48
Linux kernel image for version 2.6.31 on x86
ii linux-image-2.6.31-15-generic 2.6.31-15.50
Linux kernel image for version 2.6.31 on x86
ii linux-image-2.6.31-16-generic 2.6.31-16.53
Linux kernel image for version 2.6.31 on x86
ii linux-image-2.6.31-17-generic 2.6.31-17.54
Linux kernel image for version 2.6.31 on x86
ii linux-image-generic
Note that even though I rebooted the machine, still the old kernel
(linux-image-2.6.31-14-generic) gets selected. At reboot time I checked
out the grub2 menu and found that linux-image-2.6.31-14-generic is the
only boot option, even though I have newer kernels installed. Hence, I
tried to manually update grub2 then:
[~]>sudo update-grub
Searching for GRUB installation directory ... found: /boot/grub
Searching for default file ... found: /boot/grub/default
Testing for an existing GRUB menu.lst file ... found: /boot/grub/menu.lst
Searching for splash image ... none found, skipping ...
Found kernel: /boot/vmlinuz-2.6.31-17-generic
Found kernel: /boot/vmlinuz-2.6.31-16-generic
Found kernel: /boot/vmlinuz-2.6.31-15-generic
Found kernel: /boot/vmlinuz-2.6.31-14-generic
Found GRUB 2: /boot/grub/core.img
Found kernel: /boot/memtest86+.bin
Updating /boot/grub/menu.lst ... done
Ok, looks good. Doing a less /boot/grub/menu.lst
Shows me the new kernels were added to the list. However, rebooting the
machine, grub2 does not display the new kernels and instead reboots with
the only option in the list, namely, linux-image-2.6.31-14-generic.
