Bug Description
On a Lenovo x230 with secureboot enabled, I can only boot signed kernel.
Initially this was thought to be a grub2 issue but after investigation (added debug code in grub and running with debug=all), it was determined that the last thing grub does before the freeze is call a shim hook.
The current workaround is to either disable secureboot or use a signed kernel.
