sudo dmesg --notime --level=$lvl
Using the below zsh, I have produced the output included last.
It is kernel warning and error messages.
Comments.
I've heard
secureboot: Secure boot could not be determined (mode 0)
simply means it isn't enabled.
Then there are warnings regarding pci, acpi, nvme, MXM,
systemd and finally missing firmware (-2, file not found) for
nouveau. There are 14 warnings but many seems to be related to
previous ones, actually there seems to be 7 original warnings
if you will, of which 1 is secureboot and 1 is nouveau, so 5
unaccounted for, namely pci, acpi, nvme, MXM, and systemd.
Of the errors (34) they are related to 3 things, ACPI (again),
kvm ("disabled by bios"), and nouveau (again).
The nouveau errors is the same missing firmware (-2 followed
by -19) as in the warning output, and also assuming kvm is
just disabled (?), that leaves only the ACPI unaccounted for.
More comments welcome ... TIA
Note: The system works fine!

systemd[1]: /lib/systemd/system/plymouth-start.service:16: Unit configured to use KillMode=none. This is unsafe, as it disables systemd's process lifecycle management for the service. Please update your service to use a safer KillMode=, such as 'mixed' or 'control-group'. Support for KillMode=none is deprecated and will eventually be removed.
