After checking a little more it seems like the error only occurs when I
have the ubi module loaded.
I load the modules with modporbe ubi mtd=5 (mtd5 is a 2GB nand flash )

I'am starting to suspect a memory leak that could be related to the ubi.

Initially(fresh boot) the values are set correctly (printout done in
fs.c):
