Solved FreeBSD 14.3 - Installer Never Boots On Libreboot Device

[FalseInquisition]

I just recently installed libreboot on my Lenovo ThinkPad T480 with the hope I could run FreeBSD on it, but unfortunately the installer doesn't work for me.
The last things I see while booting are 'can't find /etc/hostid' and 'can't find /boot/entropy', but to my understanding these are just warnings that aren't the cause of this.
Those messages stay on screen but nothing more happens afterwards, even after 20 minutes of waiting.
I tried using both video and serial mode and both had the same issue.
Disabling ACPI shows the messages I listed then instantly reboots the system.
I'm booting using seabios (which is legacy boot) as when using the grub payload I never get to the first menu that appears.
Using bootonly, disc1, and memstick all have these exact same problems.

Specific details about my libreboot:
It has the seabios and grub payloads
It's using libgfxinit for graphics init
It's using corebootfb over txtmode
I used me_cleaner and deguard on it
I did their recommended tweak of changing the mac address of the IFD

Laptop relevant specs:
CPU: i5-8350U
GPU: UHD Graphics 620


I will note that I have no problem booting Linux, (I can even play games that use OpenGL or Vulkan) so I don't believe it's a GPU issue

Try verbose booting, see if there is a hint where the boot process gets stuck.

At the boot menu choose "7. Boot Options" (press the "7" key), in the options menu choose "6. Verbose", press Enter to boot.

You could also try to go through grub and use the chainloader.

Either way this is worth a proper bug report.

Issue solved! FreeBSD's bootloader doesn't play nicely with corebootfb, build without it and everything works perfectly
