Is this an effort to boot an ACPI-mode kernel, and then kexec a non-ACPI kernel?
Doing so could confuse the heck out of the platform firmware, which will think that an ACPI-mode kernel is still running.
Note that it is a historic artifact, now considered a bug, that ACPI uses the MPS code. We should be divorcing these two bodies of code rather than mixing them further.
