Thread: dell precision 5530 ACPI errors during tumbleweed startup

    Default dell precision 5530 ACPI errors during tumbleweed startup

    After the Dell logo is displayed, during Tumbleweed startup, I have a long list of kernel errors of the type:

    ACPI BIOS Error (bug): Failure creating named object [\_SB.PCI0.XHC.RHUB.HS01._UPC], AE_ALREADY_EXISTS (20190703/dswload2-323)
    ACPI Error: AE_ALREADY_EXISTS, During name lookup/catalog (20190703/psobject-220)
    ....
    ACPI BIOS Error (bug): Failure creating named object [\_SB.PCI0.XHC.RHUB.SS10._PLD], AE_ALREADY_EXISTS (20190703/dswload2-323)
    ACPI Error: AE_ALREADY_EXISTS, During name lookup/catalog (20190703/psobject-220)

    After suspension (sleep or hibernation) the computer is unable to resume, and I have to use hard shutdown, pressing the power button, to restart.
    I installed the last firmware from DELL (BIOS 1.14.0), and the system is up to date.

    I could solve the sleep resume problem, but not the ACPI errors.

    To resume from sleep (S3 mode, suspend to RAM) I modified the file /sys/power/mem_sleep in order to select [deep]:

    $> cat /sys/power/mem_sleep
    [s2idle] deep
    $> echo deep|sudo tee /sys/power/mem_sleep
    $> cat /sys/power/mem_sleep
    s2idle [deep]

    In addition I modified /etc/default/grub as follows:
    GRUB_CMDLINE_LINUX_DEFAULT="... mem_sleep_default=deep"
    ...
    GRUB_CMDLINE_XEN_DEFAULT="vga=0"

    and updated grub2:
    $> sudo grub2-mkconfig -o /boot/grub2/grub.cfg

    Now the sleep mode (activated when I close the laptop lid) works fine.
