    This is normal.

    It is an update coming from the update repo, a patch as it is called,
    and these often ignore vendor changes. It is an update for the standard
    or default kernel package that comes with the distribution. You are not
    using that one.

    You can ignore it. You can taboo it, so that it doesn't appear again.

    You may also install it (assuming you are configured for multiple
    kernels), but then you will have to modify the boot configuration
    manually because default boot kernel will switch to the one just
    installed (I think).

    Taboo the patch.
    That's it, I protected kernel-desktop in Yast and it worked, doesn't appear anymore
    Thank you very much sir.

    Interesting discussion in Tumbleweed and Pre-release Beta sections (particularly post #4 of this thread) suggest that the issues I experienced may relate to nVidia driver package rather than my inexperience with multiversion.

    Trust this is useful.

    One more question :

    When I upgraded kernel from org 3.4.x to 3.7.x I wasn't using ATI Catalyst drivers, so I installed those drivers after kernel upgrade, that all went fine.

    Now with kernel 3.7.x and installed ATI catalyst drivers, what would be the proper way to upgrade the kernel and use ATI catalyst drivers ?

    1) Install new kernel , reboot, install ATI drivers, reboot.
    2) Install new kernel, install ATI drivers, reboot.
    3) Something else.

    2 should work. 1 also of course but don't need 2 reboots

    Yeah, 2 was logical to me but had to ask before I try it out.

    Cheers.

It means, if openSUSE 12.2 was released with kernel 3.4, it will stay on 3.4 updates. So kernel modules built for openSUSE 12.2 should stay compatible with future kernel updates for 12.2.

    Of course you can install kernel from any third party repository or compile it yourself. But then it is your responsibility to fix any compatibility problems that it may bring.
    So what are the kernel modules? How do I know what might/might-not be compatible and how do I fix that?

Indeed it would be hard to complain about kernel 3.7 or nVIDIA driver 310.32 to openSUSE, but there are other avenues for complaints. None the less, it you want the latest stuff, you are mostly on your own.

    Thank You,
    Well, my laptop doesn't have nVIDIA. I believe it's just an Intel-integrated GPU.

    But if I wanted to try out a more recent kernel what steps would I need to take to make sure all the modules work with it or are updated to work with it?

    Ah, so this is not for anyone less knowledgeable than that.

    I assume though, I can install a new kernel and roll back if there are issues, correct?

    Yes, that's what we can do.
