drm User-defined mode not supported

[bumpyhead]

Hi folks,

I have freebsd 14.2 installed on intel alderlake i5-12400 (integrated graphics). Recently I am keeping getting the below messages in dmesg

drmn0: [drm] User-defined mode not supported: "1024x768": 75 78750 1024 1040 1136 1312 768 769 772 800 0x60 0x5

I have the below line in my /boot/loader.conf
kern.vt.fb.default_mode="1024x768"

I have the below line in my /etc/rc.conf
kld_list="i915kms cuse"

I have the below package installed from pkg
# pkg info | grep drm
drm-61-kmod-6.1.92.1402000_3 DRM drivers modules

# dmesg | grep drmn0

Is there an easy fix to get rid of the kernel complain? Thanks very much!

The problem has been fixed by modifying "1024x768" to a supported mode (in my case "1920x1080"):

# cat /boot/loader.conf
kern.vt.fb.default_mode="1920x1080"

This is too good to be true, unfortunately.

After opening the machine for 16 hours, I got the same complaints:
