Hi!
I've already disabled the HT function these days. All is OK, but it is not a solution. Same thing is happening while pfsense v2.3 install. I tested all the newest pfsense releases, none is working with 2 CPU and HT enabled - Installation hangs up ! :S
Somehow, 2 CPUs without HT is much better option than 2 threads / 1 core and 1 CPU option supported by the system.
Let's wait, maybe some day a fix will come to this issue.
