  1. Bug#405270: same here on ibm t60

    severity 405270 serious
    found 405270 1.7.22-4
    stop


    Same problem here on a IBM/Lenovo T60. When the radio switch is off, the
    system hangs with a nice:

    BUG: soft lockup detected on CPU#0!

    shortly after the ipw3945d loaded. There is nothing I can do but
    restarting the machine and switching the system on.

    Since this is happens to me on a Etch machine and causes the system to
    hang, I upgrade the severity oft this bug (makes package unsuitable for
    release).

    My Kernel Version:
    2.6.18-4-amd64 #1 SMP Wed Feb 21 14:29:38 UTC 2007 x86_64 GNU/Linux


    Cheers,

    Bastian

    Sorry, I disagree with the severity you assigned to this bug. It
    appears that the problem only affects a minor subset of machines (for
    example, I have an IPW3945 in my Dell laptop and it boots fine when
    the kill switch is on -- because of that I was not able to do much
    progress with this bug). Besides, you can blacklist the driver, so it
    is not loaded automatically, then you should be able to boot even with
    the kill switch on. It's an inconvenience, but I think it's relatively
    minor to consider it release-critical.

    Best regards,

    I don't know if only a minor subset is affected, do you have numbers I
    don't have? Maybe we can agree that a subset is affected.

    Besides that, I still think the bug is release critical and I disagree
    that the severity of a bug depends on the number of machines affected.

    Cheers,

    Bastian

    During the two and a half months that this bug has been filed, there
    were 2 people, other than the original submitter, who reported that
    they were affected by it (including you). Given the number of such
    wifi cards out there, I think it is reasonable to call it a "minor
    subset".

    It does not depend *only* on the number of machines affected. Other
    factors which I've already mentioned: the daemon works fine in a
    primary mode of operation (with kill switch off), and there is a
    simple workaround (blacklisting the module, and loading it by hand
    when appropriate). Finally, the release manager has also concurred
    that this bug is not RC.

    Anyway, to something constructive: if you can reliably reproduce the
    problem, please try replacing the start-stop-daemon call, invoking the
    daemon in the init file by one with a strace, something along the
    lines of

    strace /sbin/ipw3945 --pid-file=${DAEMON_PID_FILE} \
    --log-file=${DAEMON_LOG_FILE}

    and post the last few lines of output. Hopefully, it hangs in some
    syscall, that might give us a clue about what's going on. It would be
    also useful if you could check whether the bug is reproducible if you
    do not start the daemon by init file, but later by hand.

    Thanks,
