Laptop – so sleep mode works when I close the lid and then hit resume.

working as designed

description: |
  This kernel-tmb update is based on the upstream 4.14.13 and and fixes
  several security issues.

  The most important fix in this update is for the security issue named
  "Meltdown" that is fixed in theese kernels by enabling kernel Page
  Table Isolation (KTPI). Note that according to AMD, this issue does
  not effect Amd processors, so it is not enabled by default on systems
  using Amd CPU.

  The list of known security fixes and mitigations in this kernel:

  kvm: vmx: Scrub hardware GPRs at VM-exit. This enables partial mitigation
  in kvm for the security issue named "Spectre" (CVE 2017-5715, CVE 2017-5753).

  Systems with microprocessors utilizing speculative execution and indirect
  branch prediction may allow unauthorized disclosure of information to an
  attacker with local user access via a side-channel analysis of the data
  cache (CVE-2017-5754, "MeltDown").

  A use-after-free vulnerability was found in network namespaces code
  affecting the Linux kernel before 4.14.11. The function get_net_ns_by_id()
  in net/core/net_namespace.c does not check for the net::count value after
  it has found a peer network in netns_ids idr, which could lead to double
  free and memory corruption. This vulnerability could allow an unprivileged
  local user to induce kernel memory corruption on the system, leading to a
  crash. Due to the nature of the flaw, privilege escalation cannot be fully
  ruled out, although it is thought to be unlikely (CVE-2017-15129).

  The KVM implementation in the Linux kernel through 4.14.7 allows attackers
  to obtain potentially sensitive information from kernel memory, aka a
  write_mmio stack-based out-of-bounds read, related to arch/x86/kvm/x86.c
  and include/trace/events/kvm.h (CVE-2017-17741).

  The kernels are also fixed to allow loading cpu microcode for Amd
  family 17 (Zen) processors.
