Title:
  Kernel causes HDMI Audio, network cards to stop working

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I noticed when i restarted my laptop (HP 630 after installing the
  latest stable linux kernel (linux-image-13.110.13-generic:amd64
  13.11.0-13.20), there was no sound, i could not connect to the
  internet via either cable or wireless and the graphics was slow. On
  further inspection i found out no network manager displayed "network
  devices available" and there was a  dummy output in sound settings.

  After searching the internet i came across this link ---> http://askubuntu.com/questions/294016/no-sound-in-ubuntu-13-04-only-dummy-output-device-listed
  After following the instruction and choosing an earlier version of kernel (3.11.0-12-generic), all the  issues were resolved.  I have ubuntu 13.10 installed.
  Below is the comment that helped. Hope this is helpful in some way to deal with the issue with the latest kernel.


  
  "I also had it - Does sound work before reboot after one update? If yes it is probably the same.
  It's bug related to kernel 3.8.0-18.

  
  Run uname -r to check your version of Kernel. If it is 3.8.0-18-generic - try next steps
  Reboot and in GRUB select Advanced options
  Chose Ubuntu with Kernel ... (Any before -18)
  Also you can subscribe this bug at Launchpad, I hope they will fix it soon"
