    Hm, I wonder why 'platform' isn't there.

    Perhaps the dmesg log will tell.

    [/me looks]

    No, it doesn't. The BIOS evidently supports S4.

    [/me looks into the source code]

    I have no idea whatsoever how it is possible to have

    "ACPI: (supports S0 S1 S3 S4 S5)"

    in the log and not to have "platform" in the output of "cat /sys/power/disk".

    Can you please add

    printk(KERN_CRIT "PM: hibernation_ops = %p\n", hibernation_ops);

    at the end of kernel/power/disk.c:hibernation_set_ops() and see if it gets
    printed during boot?

    Thanks,
    Rafael
