We made more investigations of this problem. Joakim has assisted us to understan the patch. This patch can't break PLR feature on NAND. The only way it affects on tests is timing. So commit roll back will not fix the problem, but hides.

Now we are collecting more information about the problem. We will let you know as
soon as we find something interesting about it.
