Thank you for that. I have replicated the fault on one of our partners HW and verified that your patch fixes the problem.

I will raise a JIRA issue and prepare a changeset for review based on your patch.

Your patch failed to apply cleanly because the lines were wrapped at 72 chars. I have manually fixed this in order to apply the patch.

It is much better if you can put the patch on a web server and post a link. This avoids any problems with mailers mangling the patch. You may use people.linaro.org for this.

Thanks for your contribution,
