  Backport recent bbr bugfixes to 4.10 kernel

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  4.10 kernel is commonly used to test BBR Congestion Control
  deployments.

  Recent net-next pull in 4.13-rc1 had a bunch of fixes for the initial BBR 
release, namely:
  4aea287e90dd61a48268ff2994b56f9799441b62 tcp_bbr: cut pacing rate only if 
filled pipe
  f19fd62dafaf1ed6cf615dba655b82fa9df59074 tcp_bbr: introduce 
bbr_bw_to_pacing_rate() helper
  79135b89b8af304456bd67916b80116ddf03d7b6 tcp_bbr: introduce 
bbr_init_pacing_rate_from_rtt() helper
  1d3648eb5d1fe9ed3d095ed8fa19ad11ca4c8bc0 tcp_bbr: remove sk_pacing_rate=0 
transient during init
  32984565574da7ed3afa10647bb4020d7a9e6c93 tcp_bbr: init pacing rate on first 
RTT sample

  All of them marked as 'Fixes: 0f8782ea1497 ("tcp_bbr: add BBR
  congestion control")', which makes them legitimate bugfixes.

  All of them constrained to `net/ipv4/tcp_bbr.c` and should be trivial
  to cherrypick into 4.10.

Title:
  4.8.0 kernels do not complete boot process on VM

Status in linux package in Ubuntu:
  Confirmed
Status in linux source package in Yakkety:
  Confirmed

Bug description:
  On my native amd64 box, 4.8.0-15 works just fine, but on my VMWare
  Fusion 8.5 system, none of the 4.8.0 kernels complete the boot
  process.  I tried 4.8.0-15 from yakkety and 4.8.0-16 from yakkety-
  proposed.

  Currently  I am seeing the last message in my console at boot up as:

  [ OK ] Started Bluetooth service

  and then... it just sits there.

  Through the use of snapshots, restores, and package bisects, I've
  definitively narrowed it to linux-generic linux-image-generic and
  linux-headers-generic.
