  After this sequence, the server will lockup solid, and even REISUB will
  not reset it, it requires either hardware reset or power cycle.
  
  It happens about 3 times a week (it has a function as file server for
  other linux machines), and only started happening after upgrade from
  saucy to trusty.
  
  Hardware has been tested, with no obvious errors.

  After this sequence, the server will lockup solid, and even REISUB
  will not reset it, it requires either hardware reset or power cycle.

  It happens about 3 times a week (it has a function as file server for
  other linux machines), and only started happening after upgrade from
  saucy to trusty.

  Hardware has been tested, with no obvious errors.
