Yes, and it has the same bug although it is located
in a slightly different place.

A few minutes ago, I posted a patch to delete the extra lines.

The code is clearly wrong.  I booted on an 8p AMD box and
had no problems. Apparently the kernel (at least basic booting) is
not too sensitive to incorrect apicids being returned. Most
critical-to-boot code must use apicids from the ACPI tables.
However, the bug does affect numa node assignment. And probably
other places, too.
