I am still preparing this and I do not have access on > the hardware until Friday. Today I was able to build the system with dm-crypt (using LUKS2 and PBKDF2) and successfully boot from sdcard.
But when booting from the ubiblock device, I get the same null pointer dereference as for dm-verity.
This really seems to be related to devicemapper interfering with the ubiblock device.
To add some more details on the setup, here is the output of ubinfo:
