This happened for me yesterday, when booting the main Ubuntu 20.04 beta x86_64 iso on real hardware (not a virtual machine). It has a graphical splash screen but in the upper left corner I get this "console" message. Then eventually in a few seconds, after it has fully booted, that splash screen is replaced and the system has booted up fine. But it's a worry- producing message that should really not be there. If the kernel is actually able to handle the stock ISO's initramfs, then please change the kernel boot process to not produce an error message when there is no error.

If I "update-initramfs" using gzip instead of lz, then boot up passes without decoding failed message. --- However, we currently believe that the decoding error reported in dmesg is actually harmless and has no impact on usability on the system. Switching from lz4 to gzip compression, simply papers over the warning, without any benefits, and slows down boot. Kernel should be fixed to correctly parse lz4 compressed initrds, or at least lower the warning, to not be user visible as an error.
