So looking at that destination pointer value (ffff10043c803e8c), it
*looks* like a pointer. Almost. If it was 0xffff80.. instead of
0xffff10.. it would probably be a fine pointer.

Can you send me the config? I'm wondering what else might be close to
that load_balance_mask percpu allocation, that migth perhaps have
overflowed and written a stray byte into the pointer or something?
