You might find this document has useful information on scancodes:

http://www.win.tue.nl/~aeb/linux/kbd/scancodes-10.html#ss10.1

It seems that perhaps you have pressed a key that emits an unknown
scancode. I have seen this before on older laptops when typing the Fn
key. You might also see it when using extended keys on multimedia keyboards.

Can you determine if these are generated while using the text console or
instead inside X11?

What keyboard mapping are you using?
