    Subject[2.5.75] S3 and S4

    Hi,
    I've been playing with ACPI and software suspend.

    I have an AthlonXP on a KT333 motherboard. Kernel UP with preemption.

    S3 doesn't work with FB (well, I can suspend the machine but the screen
    isn't restored on resume. I can blindly login and reboot) but I read on
    fbdev that this is a WIP. Without FB the system goes to sleep with some
    warnings (we call local_bh_enable with interrupts disabled):

    And then the resume:

    I'm a bit worried about these MCEs, but the machine seems stable after
    resume (btw, I remeber that Alan once posted a MCE decoder, but can't
    find it - any clue?).

    S4 suspends fine, but it seems that it doesn't like preemption on
    resume:
