I don't have a reproducer other than install the kernel and wait 24h as that's how long it took for some systems to panic...
>From a very quick look, those kernels are mainline kernels, unfortunately all my hosts are LXC hosts using unprivileged containers with overlayfs, so I need kernels with the Ubuntu patchset applied for them to be usable. For now, I'll go test the current -proposed kernel on my least critical system, see if I can get that one to panic. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1404558 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.
