FreeBSD 10.3-RELEASE #0 f935af8(freebsd10): Mon Apr 18 10:58:36 PDT 2016

Since it's based on 10.3, I'd suggest booting from a 10.3 CD or memstick 
in "Live CD" mode and testing suspend / resume from there, just to rule 
out any possible differences with the FreeNAS configuration?  If this 
problem then persists, people can test against a more familiar baseline.

It's section 11.13.2.5 in the current online Handbook.

Have you tried it without (from your sysctl hw.acpi)
hw.acpi.handle_reboot: 1 ?

Have you tried with the advice from (online) section 11.13.2.2, namely:
 # sysctl debug.bootverbose=1
 # sysctl debug.acpi.suspend_bounce=1
 # acpiconf -s 3

If nothing more informative turns up soon, you might want to add or 
point to a dmesg from booting in verbose mode.  From what's there now, I 
don't know whether these may be significant?

ACPI Error: [\134_SB_.PCI0.XHC_.RHUB.HS11] Namespace lookup failure, AE_NOT_FOUND (20150515/dswload-219)
