Found what's causing the 100% CPU usage.  12 years ago, 0149ab7c6 disabled the
'hlt' instruction in include/grub/i386/time.h::grub_cpu_idle(), noting "this
can't work until we handle interrupts."  This later made its way into
include/grub/x86_64/time.h as well.

Can someone confirm if this is related ?
