It is the lack of initialization of hardware on a FastBoot startup why
hardware that was hung, or in an inoperable state, remains so.  FastBoot
copies a memory image of the kernel and drivers in their state at that
time, and restore those states on startup.  Even if the hardware gets
the CPU reset on a cold boot, FastBoot is going to reinstate its memory
image of the kernel and drivers.  The kernel and drivers are NOT loaded
on a FastBoot.  They are resumed from a saved state.  That the memory
image of states doesn't match hardware state is why FastBoot causes
problems.  When rebooting to attempt troubleshooting, FastBoot can make
the boot-time menu disappear so fast the user has no chance of hitting a
key to get it recognized to go into troubleshooting mode, or make a
selection from a boot menu.
