[U-Boot] UBI attach issues

Dear u-boot team,

Occasionally, I get corrupted rootfs if the system power goes away while u-boot is attaching the root file system in order to fetch the kernel.

I am using imx6 Solo and u-boot 2013-10.

Is there any way to stop uboot messing up the file system while making attachment of UBI? Does the latest u-boot provides a better way to protect the ubi file system during attachment.

Any advice or guidance will be very much appreciated.

Andy
