    Default How to upgrade to a newer kernel

    Hello everyone. I'm doing some tests on openSUSE 12.2 64bit and so far everything is working great.
    The last thing I want to test is a Kernel upgrade. I'm using "3.4.28-2.20-desktop" and I'd like to know what are the new stable ones (like 3.8.x-x)and how to upgrade to them =)

    Thanks

    Why the hurry?

    Here it is 2:33, Sunday night, I'm sleepy, watching a CSI movie, and
    eating strawberries with concentrated milk instead of whipped cream 8-)

    So...

    I can not recommend you a kernel to try, it is not something I do unless
    I have a reason to do so. And you have not stated one.

    I recommend you edit "/etc/zypp/zypp.conf" and adjust "multiversion" and
    "multiversion.kernels" appropriately, so that you can keep several
    versions of a kernel and see them in YaST.

    If the above paragraph is unclear, suggest you google those terms
    restricting the search to these forums, you will find several hits
    faster than I can type them >:-)

    Well, I glad that you have asked. One way to upgrade your kernel is to compile your own, and anyone can do it using SAKC:

    @robin listas: Performance. On the current kernel my performance on some things are slower. For example, extracting 16GB folder took 12 minutes, same as Ubuntu 12.04 with Kernel 3.2.x. On Ubuntu 12.10 extraction was done in 4:58 minutes, same as Mint 14.

    @jdmcdaniel3: you did this just so I wouldn't create enough courage to learn how to? LOL I downloaded the 3.8 Kernel on the repositories. It installed fine, but after reboot the system froze when those white balls are moving.

    Were the file systems the same on all those versions? What kind of extraction
    were you doing? In addition, any serious test of file performance needs to start
    with exactly the same starting position. To do that, you need to have loaded the
    fs just before starting the test.

    I have been running 3.8 kernels without many problems since 3.8-rc1.

    Your statement that it froze when the "white balls are moving" is useless. You
    need to hit the <ESC> key when that splash screen appears, and tell us what the
    system was doing when it froze.

    Both systems were tested when the fs just started AND after an hour or so of using. In all tests, kernels newer than the one openSUSE is currently using make better results for me.

    I'm currently understanding how to update the kernel on Linux Mint and will test Steam and see if there's still memory dumps here. I'll try it again tomorrow.

    Just press the ESC key while the balls are moving and break out of Plymouth display. You can see what the kernel is doing and often it prevents a graphic lockup. Try it and see.

    What is "extracting 16GB folder"? Please specify the commands you were
    using, what destination and origin filesystems, etc. To be significant,
    it would have to be on the exact same files on the exact same
    partitions, and the same mount options.

    The time difference you say is too large not to be generally known.

    @jdmcdaniel3: Don't need anymore (I guess). I burned 12.3 on a DVD and I'm going to test it tonight.

    @robin_listas: I copied a 16GB game folder compressed in .tar.gz, the game is Team Fortress 2. All tests were done extracting that file to /.local/share/Steam.

    openSUSE

    After system started, extracted the archives.
    Deleted the files, rebooted.
    One hour of use, then extracted the files again.

    Same on Ubuntu 12.04, 12.10 and Mint 14 (which is based on Ubuntu 12.10)
