Console was being switched to video even if emulator fails and
causing this hang:
Scanning PCI bus 04
04 00 1095 3132 0104 00
PCIE3 on bus 03 - 04
Video: ATI Radeon video card (1002, 5b60) found @(2:0:0)
videoboot: Booting PCI video card bus 2, function 0, device 0
videoboot: Video ROM failed to map!
640x480x8 31kHz 59Hz
