Thread: kexec refuses to boot latest -mm

  1. kexec refuses to boot latest -mm

    Hi Vivek,

    I can't seem to get the latest -mm (2.6.24-rc6-mm1) to boot with
    kexec. It just gets stuck at "Starting new kernel".

    It does boot normally when booted as the first kernel.

    Any hints debugging? (x86 architecture)

    I generally try few things.

    - Specify earlyprintk= parameter for second kernel and see if control
    is reaching to second kernel.

    - Otherwise specify --console-serial parameter on "kexec -l" commandline
    and it should display a message "I am in purgatory" on serial console.
    This will just mean that control has reached at least till purgatory.

    - If that also does not work, then most likely first kernel itself got
    stuck somewhere and we need to put some printks in first kernel
    to find out what's wrong.

    Thanks
    Vivek

    Out of curiosity, how are you booting the kexec kernel? Are you doing a kexec
    -l, or a kexec -p, followed by a system panic? If its the later, what are you
    doing to panic the system? sysrq-c, custom module executing explicit
    crash-code, hang followed by nmi panic?

    kexec -l, followed by a normal reboot.

    Ok, so it reaches till here. I get "I'm in purgatory" on the console.

    Ok. So it atleast reaches till purgatory. My hunch is that it also reaches
    the second kernel but dies early in that kernel before any message can
    be printed on screen.

    Can you put some "outb()" messages on serial console in start_kernel() in
    second kernel and see up to what point do you reach.

    My 2.6.24-rc6-mm1 kernel panics during boot on 32bit box. Let me try it on
    64 bit box.

    Thanks

    One more thing. Is 2.6.24-rc6 working properly?

    Hmm..., I just tried kexeing a 2.6.24-rc6-mm1 kernel from 2.6.24-rc6 on a
    32bit box and it is working for me. That's a different thing 2.6.24-rc6-mm1
    crashes later because of other problems.

    Which kexec-tools are you using? I am using kexec-tools-testing-20071030.


    Thanks

    2.6.24-rc5 boots, so does 2.6.24-rc5-mm1. 2.6.24-rc6 does not boot, nor
    does 2.6.24-rc6-mm1. Its a regression.

    i will add more outbs and respond back and try a bisect if that does not
    help.

    I've no clue what I managed to do wrong last night, probably tried to boot
    2.6.24-rc6-mm1 thinking it was 2.6.24-rc6. 2.6.24-rc6 boots, but -mm
    does not. Sorry for the noise.

    With the help of the outbs I have figured out that it is dying somewhere
    in setup_memory(). Will look deeper into it.

    So I went ahead and bisected -mm, and the culprit is git-x86. It boots
    fine before it, but with git-x86 applied, it fails to boot.

    Ingo/Thomas, could you please point me to the git-x86 tree so that I can
    bisect it? (with instructions on how to pull the -mm branch, I managed
    to pull the master branch, but not the -mm branch)

    Dropped from the regression list and changed the bugzilla entry to an -mm bug.

    Every git-foo.patch in -mm identifies where it came from in its changelog.

    The first few lines of
    ftp://ftp.kernel.org/pub/linux/kerne.../git-x86.patch
    are:

    GIT 27197ba67cbaa0e22598a10c82b10dacb1309ed8 irqs_disabled

    git+ssh://master.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-x86.git#mm



    I'm not sure what the "irqs_disabled\n\n" is doing there: maybe I added it
    by mistake. 2.6.24-rc5-mm1 correctly had

    GIT b668e28b74558b3a8277b5fde363ae5f803b36f0 git+ssh://master.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-x86.git#mm

    But still. The git URL is always there.

    sure:

    --------------{ x86.git instructions }---------->

    git-clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git linux-2.6.git
    cd linux-2.6.git
    git-branch x86

    git-pull git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-x86.git mm
    git-log HEAD@{1}.. # see what's in #mm

    (do subsequent pulls via "git-pull --force", as we frequently rebase the
    git tree. NOTE: this might override your own local changes, so do this
    only if you dont mind about losing thse changes in that tree.)

    Hi Dhaval,

    Could you give more details of your setup? I'm trying to figure out
    exactly what it is in kexec that goes goofy, but there seems to be an
    enormous number of codepaths, all different, depending on things like
    which kind of kernel. The more closely I can replicate your failure,
    the quicker I should be able to locate the problem.
