I'm not trying to use HDMI audio. I have simply clean-installed 13.04 on a Zoostorm (Clevo C5101) laptop - on which I normally run (and dual boot) 12.04 (which is stable).
With the stock 13.04 3.8.x series kernels I've tried the system completely hangs a few seconds after login, most often on the first cold boot, regardless of which app I start. REISUB works but that is all. I captured the above oops trace from kern.log.1 once.
A second problem with the stock 13.04 kernel I've suffered, which prevented me even getting a bootable system at the end of the installer, is that efibootmgr always triggers a (strangely non-fatal) kernel panic and doesn't work (nb. this laptop has an EFI BIOS and no BIOS upgrade is available). With a 12.04 USB boot stick I've got past the install issue with boot repair and an older kernel - now I am on to this problem.
I have no kernel problems on other 13.04 PCs at work (different hardware).

I was considering filing another bug because nothing is an exact match
for my issue but this matches the only stack trace I've had.

I'm currently testing the latest mainline 3.10, no hangs yet but it's
early days (3.10.12-031012.201309141044).

Title:
  3.8.0-18 HDMI/DisplayPort audio regression: Either oops or opening
  device fails with -ENODEV

Status in Ubuntu Desktop Tests:
  New
Status in Release Notes for Ubuntu:
  Fix Released
Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux” source package in Raring:
  Fix Released

Bug description:
  <Release note text>
   * There are reports of non-functional HDMI audio on various machines, even with proprietary drivers. In some cases analog built-in audio is affected too. Typically the the audio device does not show up in sound settings at all.  ([[https://bugs.launchpad.net/bugs/1169984 | LP: #1169984]]
  </Release note text>

  === Current recommended workaround ===

  Hopefully there'll soon be a proposed kernel to test instead, but if you can't wait, simplest is to:
  https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS

  === Alternate workaround ===
  IF you have no intention to use the HDMI audio, blacklisting the HDMI audio module will probably prevent this issue. The following commands should do it:
  echo "blacklist snd-hda-codec-hdmi | sudo tee -a /etc/modprobe.d/blacklisthmdi.conf
  sudo depmod -a
  (Reboot)

  ===

  Sound card is no longer detected in the latest upgrade.
