Boot messages become very tiny part way through boot

My monitor has a native resolution of 3840 x 2160.

During boot, the text is a reasonable size. Part way through the boot, the text becomes very tiny. I suspect that the system has figured out the native resolution and is using it. Once X11 comes up, I have a monitor configuration like this:
Code: 
Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        SubSection "Display"
        Modes      "1920x1080"
        EndSubSection
EndSection
After that, the text is again readable.

I do not yet understand the boot sequence enough to figure out who changes the resolution to the monitor's native resolution.

Can anyone give me a hint so I can make my boot messages readable again.

Thanks!
 
Looks like the kms module changes the resolution.
Maybe try a different vt font to make things readable first using vidcontrol -f /usr/share/vt/fonts/<font file>
Terminus is larger than the default...
 
I think the Xorg DDX driver changes the resolution (on a laptop when i915kms loads mid-boot my external display turns on); it's also tiny text on the resolution switch (I guess max res on TTY? it might default 96 DPI/not be HiDPI friendly without manual config?)

If I kldunload or don't load i915kms my laptop keeps the lower-res/bigger text, but I wonder if there's a way to set that pre-DE resolution?
 
This occurs just after these messages (the last readable ones):

uhub3 on uhub2
uhub3: <VIA Labs, Inc. USB2.0 Hub, class 9/0, rev 2.10/7.04, addr 7> on usbus1
uhub3: MTT enabled

Looking in /var/log/messages, is see that what immediately follows is:

end FB_INFO

And there it is, the i915kms driver changing the resolution to 3840x2160. I just need to find out if there is a way to tell it to use a different resolution.
One post suggested using set gop at boot time, but I am not sure if he was addressing the same situation. Trying that next.
 
what is the contents of /etc/rc.conf, specificially the "kld_list" line? If you have something that refers to i915kms or equivalent nvidia/amd that is likely the root cause
 
The kld_list in rc.conf is:

kld_list="i915kms hidraw hkbd fusefs"

I was able to fix the problem by adding this line to loader.conf.local in the /boot directory:

kern.vt.fb.default_mode="1280x720"

Thank you for your assistance. (I spent about 10 years, off and on, trying to get a FreeBSD desktop working. Once I discovered the forums, it got much, much easier.)
