Title:
  NMI watchdog: BUG: soft lockup - CPU#0 stuck for 22s! [kerneloops:814]

Status in linux package in Ubuntu:
  Triaged

Bug description:
  I'm using Ubuntu Xenial 16.04 and my computer (ASUS M32BF) will
  randomly freeze up, sometimes before the login screen, sometimes while
  I'm in the middle of using a program. This sometimes happens on the
  Wily 15.10 live cd as well, and on both kernel 4.3.0-2, and kernel
  4.2.0-22.

  This soft lockup happens either in kerneloops or swapper/0.

  This might have something to do with networking, because the soft
  lockups appear happen immediately before or after some network-related
  stuff. nm-applet says NetworkManager is not running, but "service
  network-manager status" says it is. "service network-manager stop"
  does not work, and I need to "kill -9" the pids for the processes.
  After starting the service after killing it, it the nm-applet's "Edit
  Connection" works for a few moments, then it won't delete any
  connections, and when closed, it won't re-open. At then end "kill -9"
  won't even work anymore (the processes get parented to init, but do
  not die). Usually, however, I never even see the login screen.

  I've been able to boot into the Wily livecd by using Windows 10 ->
  Shift-Restart -> UEFI Settings -> then booting my USB with the livecd
  (often soft lockups without going through windows).
