Hi Arthur,
	It would be great if we could capture the text as in the

	http://www.users.on.net/~arthur.marsh/20150915547.jpg
	I guess a serial console could help us to capture those
log messages. To use serial console, we need to setup serial cable,
configure grub and kernel to use serial port as console.
Thanks!
Gerry
