Console: switching to colour frame buffer device 60x50
BUG: scheduling while atomic swapper/1/0x00000002

then it gets "scrambled", but I see the following functions:
device_attach
bus_probe_device
driver_probe_device
bus_for_each_drv
platform_drv_probe
schedule
fbcon_takeover
device_attach

I guess the 'scheduling while atomic swapper' happens in fbcon_takeover()
Right?
