missing early linux console output when using SeaVGABIOS
When building using our "free" config (mv config-xxx backup-config-xxx && mv free-config-xxx config-xxx && ./build.sh) we don't have early linux boot console output on the display.
- How does GRUB behave when
GRUB_TERMINAL=consoleis set? - Can we find or file a bugreport in seabios for this?
Also, GRUB doesn't use the full screen in the framebuffer, but that's probably fine. It uses the same resolution as with Intel's vga bios binary.

Do you have the coreboot framebuffer driver (GOOGLE_FRAMEBUFFER_COREBOOT) selected in the Linux configuration?

I didn't, but changed that now which doesn't help though. It feels like GRUB needs a change here because it's "loading init ramdisk" keeps displayed until Linux graphics takes over.

Why do you think, GRUB needs a change. It seems to be doing everything fine. By the way, what GRUB version do you use?
Anyway, please paste the Linux kernel messages.
I'm running Debian stable's GRUB 2.02~beta3-5+deb9u1
dmesg is ok and unchanged. It's only about display behaviour during booting. With SeaVGABIOS GRUB is being displayed until Linux does modesetting and systemd's messages are displayed.
I only suspect a GRUB config might change that. I'm sure at all. When using Intel's vga bios, all early kernel messages are displayed in low resolution until Linux switches graphics mode.

Please try a newer one, best built from GRUB’s master branch.

That is good to know, but I’d like to take a look at those.
I can try installing a new GRUB at some point... Are there specific relevant changes?
