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 radeonfb: FIFO Timeout !
