    Re: Kernel 3.12-rc3 is here

    Have been compiling my own kernel lately in an efffort to keep my system as lean as possible. Even on this old box it's fairly quick, thanks to localmodconfig.

    Code:
    paul@lubuntu-64:~$ cd /usr/src
    paul@lubuntu-64:/usr/src$ tar jxvf ~/Downloads/linux-3.12-rc3.tar.bz2 # downloaded from https://www.kernel.org/pub/linux/kernel/v3.x/testing/
    paul@lubuntu-64:/usr/src$ cd linux-3.12-rc3
    paul@lubuntu-64:/usr/src/linux-3.12-rc3$ make-kpkg clean
    paul@lubuntu-64:/usr/src/linux-3.12-rc3$ make localmodconfig # only enable what is needed for running system
    paul@lubuntu-64:/usr/src/linux-3.12-rc3$ make menuconfig # no further changes made
    paul@lubuntu-64:/usr/src/linux-3.12-rc3$ time fakeroot make-kpkg -j3 --initrd --append-to-version=-custom2 kernel-image kernel-headers # member of src group so not compiling as root

    There may be "use single pass kallsyms" changes coming to speed up kbuild (perhaps too late for this cycle):

    So far no issues here. Temps seem to be much the same but good and snappy.

    I'll give it a whirl in the morning, between meetings. Might solve my AT&T WiFi problem in this hotel...

    w00t!

    Just installed 3.12-rc3 on this laptop, and the wifi is now working.

    It was working all across the country, but not at this hotel.

    Will little wonders never cease?!?!?!?

    EDIT

    Man, this is great. Been running all over the hotel, for 5 hours.

    Every WAP I've run across is connecting now -- zero worked before.

    Two thumbs up for 3.12

    @Paul_in_London

    Wow. Thanks for the post (#3). This was the easiest kernel compiling how-to I've seen in a long time. Are there any caveats about this method that users should be aware of (beside no support from Ubuntu of course)?

    Cheers,
    Harry in Prague

    Worked a treat, Paul.

    @rimez: Thanks. I totally missed Paul's post, when I was on the trot, last week.

    I quit compiling kernels, some time ago. The method I was using took around 4 hours on this box -- almost as long as doing security updates on a winders machine. LoL!

    I used Linux 3.10.15 as a test. It was a nail-biter. I thought I had plenty of space on my root partition, but by the time it completed, I was at 0% (.25 GB remaining). Whew!

    I never did get a 'time' reading, but I judge it took <= an hour. w00t!

    I'm running under Linux 3.10.15 right now...

    Code:
    vindsl@Zuul:~$ uname -aLinux Zuul 3.10.15-custom2 #1 SMP Sun Oct 6 10:13:10 MST 2013 i686 i686 i686 GNU/Linux
    Can't wait to try it on 3.12-rc4.
