Hmm.. hard to say, can you enable debug (not only in UBI) and
maybe try current mainline U-Boot?

The line "UBI error: vtbl_check: bad CRC at record 0: 0x88cdfb6, not 0xffffffff"
... it seems, you have some problems reading your flash ... can
you try a to write into your flash, reread the content and
compare it?

Thanks!

bye,
Heiko
