The patches are applied.

thanks

Hi IBM,

Please note that as of now the fixes for this issue have been applied on Artful (4.11 based) kernel only.

The latest submission to the kernel-team mailing-list of this patchset (v4) still needs to reviewed and applied to the Zesty kernel tree (4.10 based) before they are available on zesty/linux and xenial/linux-hwe kernels.

Thank you.

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!
