Title:
  Freezes every 30-35 seconds

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Hello

  Since a few kernels back (or some other package?!) I get freezes every
  ~ 30-35 seconds. I can see this because if I play a video, it freezes.
  If I type something, it freezes. If I move the mouse pointer, it
  freezes.

  I ONLY get this while having a external monitor connected via
  DisplayLink. Either directly to the laptop or via myu docking station.

  Computer is Lenovo T520 and I have the Thinkpad Mini Dock Series 3.

  Monitor is a 24" Samsung widescreen.

  Rebooting does not help. This is 100% reproducible.
