Ah, I realise I did not include enough context, sorry.

This _is_ in the code which sets SLP_EN:

        /* Insert SLP_ENABLE bit */

        PM1Acontrol |= sleep_enable_reg_info->access_bit_mask;
        PM1Bcontrol |= sleep_enable_reg_info->access_bit_mask;

        /* Write #2: SLP_TYP + SLP_EN */

        ACPI_FLUSH_CPU_CACHE ();

        status = acpi_hw_register_write (ACPI_MTX_DO_NOT_LOCK, 
ACPI_REGISTER_PM1A_CONTROL, PM1Acontrol);
        if (ACPI_FAILURE (status)) {
                return_ACPI_STATUS (status);
        }

        status = acpi_hw_register_write (ACPI_MTX_DO_NOT_LOCK, 
ACPI_REGISTER_PM1B_CONTROL, PM1Bcontrol);

<-- this is the point I highlighted before

        if (ACPI_FAILURE (status)) {
                ACPI_DEBUG_PRINT ((ACPI_DB_INIT, "X6failed\n"));
                return_ACPI_STATUS (status);
        }


In the light of this, is there anything you would like me to try?
