Btw, if I enable CONFIG_X86_5LEVEL with 4.15-rc1 on an AMD box, the box
triple-faults and ends up spinning in a reboot loop. Even though it
should say:
early console in setup code
This kernel requires the following features not present on the CPU:
la57
Unable to boot - please use a kernel appropriate for your CPU.
and halt.
A kvm guest still does that but baremetal triple-faults.
Ideas?
