I merged the Base Power9 patches on top of Ubuntu-4.8.0-32.34 kernel.

You can find them at https://github.com/leitao/ubuntu-yakkety/commits/power9.

The following extra commit were required also:

* 60b00025641e2921dcfba4d54b6cf7f0c5903677 #required for 520ed5b
* 520ed5b04f3e807e5bf1b6981ffb50524632fc5f #required for 18201

It also fails to build if you do not backport the following commits also:

* bee8b3b56d1dfc4075254a61340ee3898a732e63
* ccf17c8b5c8465750a6c514be9ef6f5b156b6c67
* 049d567af209b093eefa9f26eae6e15226db3520

Other than that, yakkety kernel already contains the following commits:

* 1f0f2e72270c089c291aac794800cc326c4c05dd
* 05af40e885955065aee8bb7425058eb3e1adca08
* 1a34439e5a0b2235e43f96816dbb15ee1154f656
* bd77c4498616e27d5725b5959d880ce2272fefa9

Let me know, and I can do the same for the KVM patches.

Breno - it seems that we overlapped as I did not see comment #3 until I refreshed this page. Please check my mailing list submissions for completeness.

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

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!
