    SubjectRe: [PATCH] stack2core: show stack message and convert it to core file when kernel die

    I understand that. What I'm saying is that all the additional noise
    you're causing the kernel to create is just a pure duplication of
    what we already dump.

    Oops dumps are already noisy enough - especially if they cause a panic
    at the end (where you end up with two backtraces.) We do not need even
    more noise caused by needless duplication.

    You can get everything you need already from the kernel. On ARM, we
    already dump out all the registers and the _full_ stack. There is no
    need for you to implement your own register dumping code and full stack
    dump on top of that again.

    So, I'm not going to accept your patch for the ARM kernel. Please use
    what's already provided - it's more than adequate. By doing so, you
    don't penalise those of us who want to read the raw oopses.

    Talking about noisy oopses, I'm getting one with 2.6.33-rc2 on 'poweroff'
    shutdown. No idea what it is because most of it's scrolled off the top of
    the screen and I can't scroll back. Not bothered about it at the moment.
    What it does illustrate though is why making things too noisy when problems
    occur makes it _more_ difficult to find out what went wrong.
