Start with this:

If you cannot isolate the error - I cannot do it as well for sure. So
please, try to fine one specific thing which you think is a problem, and
ask to help with that specific thing. The above link should help. In
general, the first things you need to do are:

1. validate your mtd device with the test - this is always good thing to
do.
2. enable UBIFS debugging (not debugging messages)
3. report the issue properly as it is described at the MTD web site.

WRT. reboot: if your 'reboot' command results in 'recovery needed' then
your 'reboot' command does not unmount the file-system and just reboots
it. Of course from UBIFS's POW this is a power cut and it needs
recovery. But there is nothing to be afraid of if you know you synced
your files. So you need to take a look what "reboot" does - it may do
completely different things on different systems. E.g., does it sync the
data? does it unmount FSes?
