Title:
Kernel panic when used with upstart after 0.11-4ubuntu2.1 update
Status in json-c package in Ubuntu:
Triaged
Bug description:
Installing the 0.11-4ubuntu2.1 security update on a Xenial system with
upstart installed, the system crashes with a kernel panic.
The error message is:
[ 99.992278] Kernel panic - not syncing: Attempted to kill init!
exitcode=0x0100
[ 99.992278]

[ 99.996057] Kernel Offset: disabled
Downgrading to libjson-c2_0.11-4ubuntu2 resolves the issue.
Steps to reproduce:
* Create a system with Xenial installed (I'm using an AWS instance with AMI
ami-0f2ed58082cb08a4d)
* Install upstart: apt-get install upstart-sysv
* Reboot
* Update apt and upgrade the packages: apt-get update && apt-get upgrade .
This causes the kernel panic.
* To repeat the kernel panic, run dpkg --configure -a
