First of all, run the mtd tests and see if the flash works well.

Another problem I know with SPI flashes is that UBIFS uses vmalloc'd
memory for I/O, which is not suitable for DMA-ing on ARM platforms and
may cause subtle bugs and curruptions. Can you try to disable DMA and
see if the issues go away?
