“There appears to be no BMC at this location” message during the 18.04 boot

I upgraded 16.04 to 18.04, it wasn’t a breeze, after reboot, it takes so long in the ASUS screen (this used to be case in 16.04 era), then a short purple screen and linux boot messages scroll. In the stopped screen (I believe it will boot up to the gui scree in the end), I see two fail messages.

(!(enter image description here)(1))(1)

What can I do in this case? (for the “There appears to be no BMC at this location” message)
