Comment 54 for bug 126140

Luiz, thanks for the usptream reference. The patch you mention was recently applied to the Intrepid kernel when it pulled in the upstream 2.6.27.5 patch set - see Bug 296500:

    ALSA: hda - Add reboot notifier

    commit 0cbf00980f0fc4cc064a15ab3dfce19b5fae9130 upstream

    The current snd-hda-intel driver seems blocking the power-off on some
    devices like eeepc. Although this is likely a BIOS problem, we can add
    a workaround by disabling IRQ lines before power-off operation.
    This patch adds the reboot notifier to achieve it.

    The detailed problem description is found in bug#11889:

The Ubuntu kernel which contains this patch is still making it's way into the intrepid-proposed repository. If you can please monitor bug 296500 for when the kernel is available for testing in intrepid-proposed and provide feedback after testing that would be great. For information on how to enable -proposed, please see https://wiki.ubuntu.com/Testing/EnableProposed . The wiki uses 'hardy' in it's examples, so please make sure to use 'intrepid' instread. Thanks.
