I agree to that part.

But not completely here: If I don't have a serial console attached (in
fact I never even tried to), then the information *IS* lost. Hence this
should still be configurable, but you may clearly chose a default mode
that in fact does reboot immediately.

Further, as indicated, x86_64 behavior is different from i386's, which
already points to pre-exisiting consistency issues.
