Hi Stephane,

Can you see if this issue was already fixed in the latest 3.13 upstream kernel:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13.11-ckt13-trusty/

If it was not, we can bisect the issue.

It might also be worth testing the latest mainline kernel, to see if this issue came down from upstream:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.19-rc2-vivid/

Title:
  IPv6 related kernel panic following upgrade to 3.13.0-43

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  After updating a dozen machines from 3.13.0-40 to 3.13.0-43, they all
  kernel panic within the next 24 hours.

  I managed to pull the console from one over an IP KVM and it shows a panic related to IPv6 networking:
  https://dl.stgraber.org/panic-3.13-43.png

  All affected machines had native IPv6 connectivity to the Internet.

  Downgrading to 3.13.0-40 resolved the issue (so it's clearly a
  regression) and upgrading to lts-utopic 3.16.0-28-generic also
  appeared to do the trick.

  
  A friend also just reported seeing the exact same problem on his server which also has native IPv6 connectivity so the issue appears pretty widespread.
