U-Boot, video console, and visual artifacts
My apologies for the delayed response.

I use Gentoo with Manjaro kernel 5.11.16 and that works, but using even vanilla 5.11.16 fails to display anything. I found that using I have to use two Manjaro patches to get display working and they are still present in Manjaro's repo:

I'm not sure how the screen behaves on 5.13, my experience is with 5.11.16. I'm now planning to upgrade to 5.13. I use uboot 2021.07.

Thank you very much for providing this feedback!  I've had a rather detailed look at those two patches, but I'm still not exactly sure why are they required to make the video output work.  I'll have another look at that.

See https://lists.denx.de/pipermail/u-boot/2...53338.html (no response, alas)

Right, that's a rather benign error message, as I've already explained in one of my earlier posts.
