    No, here it is:
    [ 0.000000] ACPI: Override [DSDT-F3J00001], this is unsafe: tainting kernel

    Problem with AE_ALREADY_EXISTS is that that is quite rare.
    I'll continue watching.

    At the moment:
    [ 0.165424] ACPI: EC: Look up EC in DSDT
    [ 0.181759] ACPI: Interpreter enabled
    [ 0.181780] ACPI: (supports S0 S1 S3 S4 S5)
