Public bug reported:

[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.
