Luca, I have been having similar problems on a hacked Overo kernel.

I have no problems with 2.6.35.

I tried just commenting out the define and disabling PREFETCH and did not get 
a good boot due to ubi not finding the volume info.

Are you loading up a UBI image with uboot?

Are you using the ubi volume as rootfs?

Clearly HWECC has some advantages, but UBI and HWECC need some effort to get 
working together.
