I built a Zesty test kernel with a pick of commits 101dd590a7fa(4.13-rc3) and 09539f9(4.13-rc4). The test kernel can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1716491/

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-zesty' to 'verification-done-zesty'. If the problem still exists, change the tag 'verification-needed-zesty' to 'verification-failed-zesty'.

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!
