UbiFS + HWECC(?) + BeagleBoard = fail

[[AvataR]]

Hi. After moving to upstream 2.6.3{5,6,7} kernels, i forced to use jffs2
instead of ubifs, because of lot CRC errors. If i use prefetch/dma, i
can attach to ubi, make volume, write data, reboot - and got lots of CRC
errors. Without prefetch i just couldn't do anything to ubi. 

Looks like hw/sw bug in ubi
