It's interesting.

Can you re-mount these partitions after reboot? I would like to see
the kernel message when this mounting failed happens.

Besides, Could you mount another partition after this failure? Example,
database2 on your system. I think some calculate information goes
wrong on your global UBI layer so you can't mount partitions of your
device ubi0 any more.
