Well... that caused most of my problems.
--pad means pad to eraseblock size, not pagesize.
So the first writes in the new filesystem would cause pages in that last
eraseblock to be overwritten.
With SLC I always got away with that, but with MLC, clearly not.
(now I'm still left with lots of singlebit errors, and occasional jffs2 CRC
errors, pxa3xx_nand was obviously not meant to deal with such low quality
MLC, no action is taken on bit errors, but at least everything can be
explained now)
Thanks everybody for helping me find the cause of this problem.
Rgds, Pieter
