Title:
  BUG: soft lockup - CPU#3 stuck for 22s! [tvheadend:29245] -
  flush_tlb_others_ipi

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  This is the continuation of bug 986392.

  Since I've updated tvheadend I have the problem, that after a few hours, the servers gets stuck and is not responding to network input nor Hardware Keyboard. The attached Monitor won't even wake from Powersafe. When tvheadend is not running, the server works flawless. This bug has probably broken my raid 2 days ago, I had to rebuild it by hand (hopefully I haven't lost any data).
  I've restarted a few times in the last two days and whenever  forgot to stop tvheadend the server died after some hours.

  One time when this happened I had an open ssh session, this is the
  last output I got:
