Hi
I try to use UBIFS as root file system on NAND and I see something strange on 2.6.33-rc4
The file system is mounted as a read-write and when it boots up for first time everything is fine, but after the first reboot I have a file system crash! And it happens always.

Does anyone of you has used UBIFS with NAND on OMAP 138L EVM LOGIC board?
The software hasn't changed at all, as it comes from TI, just enabled NAND support and UBI/UBIFS
Thank you
