Hi Kernel & Release team,
I'm wondering if this bug below should be release noted, and if so, how
to do it.
It seems to hit quite a few machines - it's got 10 duplicates just in
the short amount of time the bug has been present and has the potential
to knock out audio in *a lot* of machines.

Subject: [Ubuntu-audio-dev] Heads up: Bug 1169984 will cause audio
problems, especially HDMI

Unfortunately a bug causing kernel memory corruption slipped into the
released 13.04 kernel. It is caused by a last-minute patch we backported
to try to improve HDMI audio support for Haswell, so upstream kernels
are unaffected.
Since it's memory corruption, several symptoms can appear, but the most
common seem to be:
* Sound card fails to load at all. Dmesg shows an oops in
patch_generic_hdmi
* Sound card loads, but any attempt to access it fails with -19 or
-ENODEV.
This concerns HDA Intel cards that have HDMI codecs. Depending on
hardware layout, sometimes analog audio and HDMI audio are two codecs on
the same card, in which case analog audio can be affected too.
