This bug was fixed in the package linux-aws - 4.4.0-1088.99
---------------
linux-aws (4.4.0-1088.99) xenial; urgency=medium
* linux-aws: 4.4.0-1088.99 -proposed tracker (LP: #1834908)
* hibernation support for linux-aws (LP: #1831940)
- UBUNTU SAUCE [aws]: block: xen-blkfront: consider new dom0 features on
restore
- UBUNTU SAUCE [aws]: ACPICA: Enable sleep button on ACPI legacy wake
- UBUNTU SAUCE [aws]: xen: restore pirqs on resume from hibernation.
- UBUNTU SAUCE [aws]: xen: Only restore the ACPI SCI interrupt in
xen_restore_pirqs.
- radix-tree: delete radix_tree_locate_item()
- mm: rid swapoff of quadratic complexity
- sched/wait: Fix abort_exclusive_wait(), it should pass TASK_NORMAL to
wake_up()
- sched/wait: Avoid abort_exclusive_wait() in ___wait_event()
- sched/wait: Avoid abort_exclusive_wait() in __wait_on_bit_lock()
- sched/wait: Introduce init_wait_entry()
- sched/wait: Standardize wait_bit_queue naming
- sched/wait: Introduce wait_var_event()
- mm: swapoff: shmem_unuse() stop eviction without igrab()
- UBUNTU SAUCE [aws]: mm: aggressive swapoff
- UBUNTU SAUCE [aws]: PM / hibernate: make sure pm_async is always disabled
- NVMe: Allow request merges
- PM / hibernate: Do not free preallocated safe pages during image restore
- PM / hibernate: Recycle safe pages after image restoration
- PM / hibernate: Simplify mark_unsafe_pages()
- [Config] aws: disable CONFIG_TRANSPARENT_HUGEPAGE_ALWAYS
- UBUNTU SAUCE [aws] PM / hibernate: set image_size to total RAM size by
default
- UBUNTU SAUCE [aws] PM / hibernate: reduce memory pressure during image
writing
- UBUNTU SAUCE [aws] mm, page_alloc: disable fair zone allocation policy on
hibernate
