Thanks, will check.

We also suspect it could be related to syncing.

We identified that reverting this new commit solves the issue:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=b5c26f97ec4a17c650055c83cfc1f2ee6d8818eb

Will study the LX docs and geode X driver for more clues.

Thanks,
