(In reply to Daniel Kolesa from comment #5)
Yes, cluster on die creates two numa domains per socket, then multiplied by the
number of sockets.

Load the failing kernel into kgdb, then do 'list *uma_startup_count+0xe6', the
expression is the symbolic address where the trap occured.  You might need to
use kernel.full or put kernel.debug in the right place.
