I see the same message on Linux (Ubuntu 19.04) too, so I don't think this
is a critical error.

No, that just the 16x32 built-in font being used after intelfb takes over.
Your resolution is 1366x768 as you can see in that framebuffer info. line.

Add something like this in /etc/wscons.conf to get the smaller (8x16)
built-in font:

setvar	ttyE0	font	Boldface
setvar	ttyE1	font	Boldface
setvar	ttyE2	font	Boldface
setvar	ttyE3	font	Boldface
