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.

They are, so far: commit 616badd2fb499320d3ac3b54462f55dededd0e0f Author: Alistair Popple <alist...@popple.id.au> Date: Tue Jan 10 15:41:44 2017 +1100 powerpc/powernv: Use OPAL call for TCE kill on NVLink2 Add detection of NPU2 PHBs. NPU2/NVLink2 has a different register layout for the TCE kill register therefore TCE invalidation should be done via the OPAL call rather than using the register directly as it is for PHB3 and NVLink1. This changes TCE invalidation to use the OPAL call in the case of a NPU2 PHB model. commit 1d0761d2557d1540727723e4f05395d53321d555 Author: Alistair Popple <alist...@popple.id.au> Date: Wed Dec 14 13:36:51 2016 +1100 powerpc/powernv: Initialise nest mmu POWER9 contains an off core mmu called the nest mmu (NMMU). This is used by other hardware units on the chip to translate virtual addresses into real addresses. The unit attempting an address translation provides the majority of the context required for the translation request except for the base address of the partition table (ie. the PTCR) which needs to be programmed into the NMMU. This patch adds a call to OPAL to set the PTCR for the nest mmu in opal_init(). These patches are, still, in the powerpc-next tree. == Comment: #2 - Breno Henrique Leitao <bren...@br.ibm.com> - 2017-02-22 13:33:59 == In order to support NVLink2, the memory hotplugs should be applied also, they are: 0d0a4bc powerpc/mm: unstub radix__vmemmap_remove_mapping() 4b5d62c powerpc/mm: add radix__remove_section_mapping() 6cc2734 powerpc/mm: add radix__create_section_mapping() b5200ec powerpc/mm: refactor radix physical page mapping 32b53c0 powerpc/mm: Fix memory hotplug BUG() on radix c3352cb dt: add documentation of "hotpluggable" memory property 41a9ada of/fdt: mark hotpluggable memory 114cf3c mm: enable CONFIG_MOVABLE_NODE on non-x86 arches 39fa104 mm: remove x86-only restriction of movable_node 4a3bac4 powerpc/mm: allow memory hotplug into a memoryless node Note that you need to set CONFIG_MOVABLE_NODE=y.
