Hi,
	I was testing with RELENG_11 as of 2 days ago.  The fix seems to be there

# sysctl -A hw.lower_amd64_sharedpage
hw.lower_amd64_sharedpage: 1

Would love to find a class of motherboard that pushes its "You dont need
to dork around with any BIOS settings. It just works.  Oh, and we have a
hardware watchdog too".... ipmi would be stellar.
