>> I just installed 12-CURRENT on the laptop and it also hangs even at
install/boot/shutdown until I hit keys, then it will move as long as I
continue to hit keys. I also found that if I ping the laptop, it will
respond but in between pings, it will hang. Using FreeBSD 10.3, it works
perfectly fine without any random keypresses. Any ideas?
