For what it's worth, the same thing happens in Linux 3.2.0-59-generic
i686; I don't have any older kernels still in place on either system to
see if it goes farther back than that.

Title:
  file splice in pool causes network timeout which freezes both systems

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I first noticed this about three weeks ago while scrolling through a
  large PDF file via rdesktop; finally located error messages in
  kern.log today. Symptom is sudden loss of network connection. Both
  systems involved must be shut down, allowed to cool for several
  minutes, then re-booted, to restore network actions. The kern.log
  entry indicates timeout during file-splice action but I have not found
  more detail than that.
