By default, kernel output (error messages, typically) are in green,
whereas userland output is uncoloured.

On i386, you can switch to another virtual terminal (once you have
enabled it, see below) with Ctrl-Alt-F<n>.  The kernel output only gets
sent to the console, which is usually accessed at Ctrl-Alt-F1.  Other
virtual terminals won't see it (or any other console output).

In fact, I generally disable the first virtual terminal on my machines
so that Ctrl-Alt-F1 is *only* for console output, and all user
interaction takes place on other vtys, precisely to avoid mixing error
and log messages into my user interface.

Looks like a problem with a USB drive.  What hardware is sd0?

You need to enable ttyE1 (or any others you want to use) by changing the
status from "off" to "on" in /etc/ttys.
