  1. Bug#491057: linux-image-2.6.25-2-686: Dell Latitude D610 laptop doesn't resume with 2.6.25

    Package: linux-image-2.6.25-2-686
    Version: 2.6.25-6
    Severity: important

    Hi,

    My Dell laptop, a Latitude D610, no longer resumes with kernel 2.6.25.

    During resume, there's some hard disk activity, but the screen never
    turns on. I don't think that the system started normally (ie, that it's
    only a screen problem) because pressing the power button shortly doesn't
    power down the laptop.

    It worked fine with linux-image-2.6.24-1-686 2.6.24-7. It also fails to
    work with linux-image-2.6.26-rc9-686
    2.6.26~rc9-1~experimental.1~snapshot.11825.

    After more investigation using 2.6.26-rc9:

    I could suspend and resume using acpi-support's legacy mode. The trick
    is to shutdown alsa (which acpi-support legacy mode does), and then
    add the following modules to the exclude list: snd_intel8x0
    snd_ac97_codec

    It should probably be investigated whether those modules should be added
    in some blacklist in acpi-support (I haven't tested whether snd_intel8x0
    or snd_ac97_codec is at fault). (that's why I'm reassigning to
    acpi-support)

    I couldn't get hal+pm-utils to work. Apparently, pm-utils doesn't
    shutdown alsa, so I can't remove the module. Even after shutting down
    alsa, killing mixer_applet2, and removing the modules manually, the
    laptop suspends, but doesn't resume (short disk activity, then nothing),
    when suspended using pm-suspend.

    Usually, suspend/resume should not require anything from userspace. The
    fact that some operations ("alsa shutdown") have to be done from userspace
    could be considered as a kernel bug AFAIK.

    So I don't understand why you don't leave the bug open against the
    kernel... in particular when it's clearly a regression.

    Cheers,

    I'm not sure if there's a kernel "policy" on "modules should not
    break suspend/resume". If there is, yes, it's a kernel bug that
    snd_intel8x0 or snd_ac97_codec break suspend.
