I've bisected it down to this commit:
commit 78b017cab9338a015d8c20d6b1e35f276073a35a
Author: Benoit Cousson <b-cousson@xxxxxx>
Date: Thu Nov 11 22:35:16 2010 +0100
OMAP: mux: Add support for control module split in several partitions
Just reporting for now. I'll take a stab at fixing this tomorrow,
unless someone beats me to it.
