Bug Description

Hi,

tonight many Ubuntu 16.04 Linux Servers rebooted because of kernel update 4.15.0-60-generic

Now they get a kernel panic "not syncing" - somewhere around ip_do_fragment

When we select the old kernel 4.15.0-58-generic all is running well.

The screenshot has only part of the stack trace, but it seems to be the same issue as bug #1842447.

more and more systems are crashing. All of them are used as linux router / proxy.

The crash takes some time after a reboot.

Till now I have no good screenshot of the crash, because

- keyboard and or screen don't give feedback
- I am also not at the remote suite

I checked syslog file, but the crash is not logged there.
