What kind of monitor do you have plugged in?  To HDMI?  Do you have only
one attached?  Do you have another one to try?   It looks like there is
unspected EDID data and this is not well handled.   You might read the
kernel code and try to improve the error handling to skip bad modes and
just leave the good ones, and maybe print them all out.

Does the monitor really support 3840x2160?

Does it work with other operating systems?
