Bug Description
# lsb_release -rd
Description: Ubuntu 14.04.1 LTS
Release: 14.04
# uname -a
Linux napa 3.13.0-32-generic #57-Ubuntu SMP Tue Jul 15 03:51:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
A kernel panic occurs while disabling the automatic task group creation within /etc/sysctl.conf using "kernel.
After adding the "noautogroup" kernel parameter to GRUB, the system will boot without issue.
I have attached a screen shot of the stack trace as I was unable to capture the stack trace using netconsole, linux-crashdump, and /var/log/kern.log. Oddly enough, while trying one last approach (serial console) to capture the full trace within virtual box using a host pipe and setting console=ttyS0, the system booted without issue and disabled automatic task group creation.
