Unfortunately, I have not find a way to capture the console log, no
serial for me. I am using a NVMe for my rootfs. By checking the
screen log, I see that 1 kernel message is missing:

[    4.193375] EXT4-fs (nvme0n1p3): mounted filesystem a9e1243b-332f-46ce-a5e7-cea86b44f797 with ordered data mode. Quota mode: none.
