See Documentation/acpi/initrd_table_override.txt and note that it is
important that the tables are really located at /kernel/firmware/acpi/
in your initrd (which must be the first, even before any possible
microcode updates).
What are you trying to do? For ACPI method tracing, see
Documentation/acpi/method-tracing.txt
