Title:
  echo string to /dev/kmsg fails to appear on /var/log/syslog

Status in “linux” package in Ubuntu:
  In Progress

Bug description:
  [Impact]
  In the precise 3.2 series kernel writing strings to /dev/kmsg appears and dmesg and /var/log/syslog, in 3.5 series kernel this does not happen properly even with the equivalent userspace packages.

  I've already done a coarse bisect,
  works v3.4
  fails in v3.5-rc1

  [Test Case]
  #!/bin/bash
  echo 'blah' > /dev/kmsg
  tail -n1 /var/log/syslog | grep blah
  # This should return 0.
