I built a Trusty test kernel with a cherry-pick of commit c65c7a306. Commit a5642ab4 was a prerequisite for the kernel to build correctly.

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1581585/

Can you test this kernel and see if it resolves this bug?

Thanks in advance!

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-trusty' to 'verification-done-trusty'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
