    OK, this is weird.

    But the good news is that there is a very small number of commits
    between 2.6.27.2 and 2.6.27.4.

    ftp://ftp.kernel.org/pub/linux/kerne...geLog-2.6.27.3
    ftp://ftp.kernel.org/pub/linux/kerne...geLog-2.6.27.4

    I'd be looking at these:

    commit 3b987ac961486373f91191b14291b331fa546072
    Author: Rafael J. Wysocki
    Date: Sat Sep 6 13:13:01 2008 +0200

    ACPI suspend: Always use the 32-bit waking vector

    commit a6629105dd03d370fcb31e97bddf223fa4bb651e upstream.


    commit 66036f5862883fcc9f7ff8550685a5a3de1a57e4
    Author: Rafael J. Wysocki
    Date: Sat Oct 4 00:05:05 2008 +0200

    ACPI Suspend: Enable ACPI during resume if SCI_EN is not set

    commit d0c71fe7ebc180f1b7bc7da1d39a07fc19eec768 upstream.



    presumably 2.6.28-rc3 is also broken?

    I don't know I can test it on Thu. But may be may fault or misunderstanding fist kernel which I test is 2.27.2. I don't
    test any kernel before. I don't know if 2.6.26 works.

    OK

    Please check if this commit helps
    http://git.kernel.org/?p=linux/kerne...83e79cca6fd5a3

    If not, the fastest way to find the failing commit would probably be to carry
    out bisection of kernels between 2.6.26 (good) and 2.6.27 (presumably
    bad as well as 2.6.27.2).
