I think this one
ARCH_HIBERNATION_POSSIBLE=n
because
SMP=y
since
 config ARCH_HIBERNATION_POSSIBLE
        def_bool y
-       depends on !SMP || !X86_VOYAGER
+       depends on !SMP

The condition was wrong, ok, anyway it worked. Would
depends on !SMP || EXPERIMENTAL
make sense? The smp is handled in disable_nonboot_cpus manner, right?
