Public bug reported:
In Azure, updating an instance to the latest Azure optimised fips-
updates kernel (4.15.0-2007-azure-fips) leaves the system in an
unbootable state.
The serial console shows the following and reboots:
Checking kernel image: /boot/vmlinuz-4.15.0-2007-azure-fips
Kernel integrity check failed
Rebooting automatically due to panic= boot argument
This is with the instance type Standard D2s v3
Steps to reproduce (with the UA client in Ubuntu Pro):
-Launch an Ubuntu Pro 18.04 instance on AWS on a Standard D2s v3
instance
sudo add-apt-repository ppa:canonical-server/ua-client-daily --yes
sudo apt install ubuntu-advantage-tools ubuntu-advantage-pro --yes
sudo ua disable livepatch
sudo ua enable fips-updates --beta
sudo apt install linux-azure-fips
KERNEL=$(awk -F"'" '/menuentry.*azure-fips/ { print $(NF-1); exit }'
/boot/grub/grub.cfg)
sudo tee /etc/default/grub.d/99-fips.cfg << __EOF__
GRUB_DEFAULT="Advanced options for Ubuntu>$KERNEL"
GRUB_CMDLINE_LINUX_DEFAULT="\$GRUB_CMDLINE_LINUX_DEFAULT fips=1"
__EOF__
sudo update-grub
sudo reboot
-Look at serial console in Azure Portal
Attaching screenshot of error before kernel panic and auto reboot.
