I may have experienced this issue also on bionic (18.04) with the current kernel version as of today (4.15.0-13.14).

I upgraded one affected system with "do-release-upgrade -d". After completing the upgrade and rebooting, the system froze the same way as with the affected 17.10 kernel and microcode combination. After adding "apparmor=0" to the kernel command line the boot was successful. The system has sssd.

I was not able to perform further testing today. I will try to confirm tomorrow.

Or maybe someone else with an affected system is able to try bionic as well? ISOs available at http://releases.ubuntu.com/18.04/ if needed.
