Title:
  BUG: soft lockup - CPU#1 stuck for 22s! [kworker/u16:5:142]

Status in linux-lts-trusty package in Ubuntu:
  New

Bug description:
  Kernel has been upgraded from 3.13.0-49 to 3.13.0-53, several minutes
  after the first reboot with the new kernel I noticed high wio while
  syslog was filling with messages listed below. When I tried to reboot
  (shutdown -r) it posted reboot messages to all console windows and
  then locked up - no reaction to keyboard, no ping response, had to
  powercycle it. After the reboot back to 3.13.0-49 system works fine,
  although filesystems were dirty. Didn't try it the second time - this
  system is too important for experiments. It has been running on the
  same hardware for a couple of years with no prior issues.
