Hi,
   When I install freebsd-12, my console stucks in 
      ums0 numa-domain 0 on uhub4
      ums0 :<vendor 0x12d1 Keyboard/Mouse KVM 1.1.0 ,calss 0/0,rev 1.10/1.00,addr 3>on usbus2.
  I see the serial prints:
      Please choose the appropriate terminal type for your systerm.
      Common console types are:
       ansi      Standard ANSI terminal 
       vt100     VT100 or compatible terminal
       xterm     xterm terminal emulator (or compatible)
       cons25w   cons25w terminal
Console type [vt100]:

   But I install freebsd 11.2,I enter the installation page successfully.
   What's the differences between 11.2 and 12.
   Why my console can't enter the installation page?
