wapbl panic on new system with too much memory!

I'm in the process of installing a new machine, and I'm getting a reproducible panic at boot time. The machine is a Intel Core i7-6900 (8 cores, 16 threads, 3.2GHz) on an ASUS X99-E motherboard. It is fully-populated with 8 x 16GB DDR4 DIMMs (for a total, yes, of 128GB!). Basically, I clone
