So which platform(s) is it not working with?

On a Pi4, booting to console I get raspberries for the initial part of boot (using the dumb framebuffer) and they disappear when fkms switches in.

@spaccabbomm are you booting to console or desktop. Have you enabled fkms/kms? Any non standard settings in config.txt or cmdline.txt?

spaccabbomm commented 4 years ago

I'm booting on console, here is my cmdline.txt

here the config.txt

Here is my boot video. the "loading" text is the kernel logo.

BigMuscle85 commented 3 years ago

Since Linux kernel 5, the boot logo is not displayed when "quiet" boot is enabled. see commit 10993504d647356196a04b3022d645ec92e00159
