    after hybernation doesn't resumt

    Hi All,
    I just updated from 7.10 to 8.04,all seems to work well but I lost the possibility to hybernate my laptop (sony vaio sz1m), that before worked very well.

    When I try to hybernate the laptop seems to do all usual stuffs, with only a screnn message that doesn't seem an erroes, something like "drm_sys_suspend". Then when I restart the laptop it does the normal reboot.

    In general my boot screen appears strange: the graphical boot run for few seconds but when the scripts are called the graphical bar changes in text messages.

    I'm completely new to Ubuntu myself, but have you tried putting the NOACPI flag in your boot string? It might be a power management issue. Just a thought.

    I'm not sure but suspend works well so I'd like before to try something else. dmesg about acpi in example gives this message:

    [ 0.000000] ACPI: BIOS bug: multiple APIC/MADT found, using 0
    [ 0.000000] ACPI: If "acpi_apic_instance=2" works better, notify linux-acpi@vger.kernel.org
    [ 0.000000] ACPI: DMI detected: Sony
    [ 0.000000] ACPI: PM-Timer IO Port: 0x1008
    [ 0.000000] ACPI: Local APIC address 0xfee00000
    [ 0.000000] ACPI: LAPIC (acpi_id[0x00] lapic_id[0x00] enabled)


    so I'm trying to change according this suggestion
