Linux supports two methods of overriding the BIOS DSDT:
Linux supports a method of overriding the BIOS DSDT:
CONFIG_ACPI_CUSTOM_DSDT builds the image into the kernel.
CONFIG_ACPI_CUSTOM_DSDT_INITRD adds the image to the initrd.
When to use these methods is described in detail on the
When to use this method is described in detail on the
Linux/ACPI home page:
http://www.lesswatts.org/projects/acpi/overridingDSDT.php
Note that if both options are used, the DSDT supplied
by the INITRD method takes precedence.
Documentation/initramfs-add-dsdt.sh is provided for convenience
for use with the CONFIG_ACPI_CUSTOM_DSDT_INITRD method.

You should only build ONE of the stacks, unless you REALLY know what
you are doing. If you install both, you should configure them only as
modules rather than link them statically, and you should blacklist one

blacklist firewire-ohci
