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:

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.

Might be worth mentioning that all affected hosts are x86 64bit Intel.
For those I've got access to, the issue happened on:
- 2x Xeon E3-1245v2
- 1x Xeon E5-2620v2
- 1x Atom C2750
- 1x Atom D2500
- 1x Core i5 750
All running on pretty standard Intel boards, so the usual set of Intel chipsets for their generation.
