  Sometimes userspace get locked up hard: A QEMU instance sees long hangs while the host gets suspended, USB devices/drivers lock up for some time (like in this bug's dmesg), or Google hangouts in bug 1495585.
  The kernel detects that some process(es) get hard-locked up, the hardware watchdog (which systemd configures for some crucial services to auto-restart them via "WatchdogSec=1min") picks this up and restarts the process. 

  In that case, these crash reports only describe the symptom, not the
  cause. They should be suppressed since they provide no information
  that can be used to diagnose the actual root problem.
