My boot process usually is iBoot -> m1n1 on nvme -> m1n1 chainloaded over usb.
I thought I exercised this path by turning off the init in m1n1. I didn't take
into account that this would only affect the one loaded over usb and that
the one on nvme would still intitialize everything.
Thanks for fixing this!
