I'll look around for that patch. I seem to recall one of my 9.3 systems needed it. You know if you need it if freebsd-update says cowardly refusing to proceed.

I have not used a VNC console, but have used a serial console which was not all that reliable. I suspect the issue was with the equipment connected to the serial port, not FreeBSD.

I tried to upgrade one system from 9.3 to 10.something and it would not boot. It died during the hardware discovery. I gave up and went to 11.0 which worked just fine on that hardware.
