I went to 3.16-rc6 and then reapplied three patches from your previous
email messages. The dmesg output and the diff from 3.16-rc6 have been
added to https://bugzilla.kernel.org/show_bug.cgi?id=80251 .
The dmesg output is at: https://bugzilla.kernel.org/attachment.cgi?id=143961
The combined diff is at: https://bugzilla.kernel.org/attachment.cgi?id=143971
What I think you are probably looking for in the dmesg output:
