I am having this issue too.
Mac Pro 6.1 late 2013
2.7 GHz 12 core Xeon E5
128 GB 1066 DDR3
AMD Fire Pro D300
Open Core 4.5 does enable universal control, but the system reboots after 60 seconds wether I login or not. It seems to cause a kernel panic and will reboot endlessly if allowed to do so. I have tried just about every variation configuring open core but no luck.
Crash log:
