Public bug reported:
The Linux kernel has issues when secure boot is enabled and PTT enabled.
For starters, it causes the machine to boot twice every time I restart.
In addition, the kernel and OS is just slow. This only happened after
installing Ubuntu with secure boot enabled, and MOK manager on.
The machine should boot once, load the signed modules and kernel stuff,
and load Ubuntu without issue.
