My question for you is when I review log with 'journalctl -b' I see two lines, relating to, I think - Unknown kernel command line parameters . The two lines are below.
Thinkcentre-M57p kernel: Kernel command line: BOOT_IMAGE=/boot/vmlinuz-6.8.7-1-default root=/dev/mapper/system-root resume=/dev/system/swap nvidia_drm.modeset=1 splash=0 plymouth.enable=0 mitigations=auto nosimplefb=1 security=apparmor Apr 21 10:45:44 paul-Thinkcentre-M57p kernel: Unknown kernel command line parameters "BOOT_IMAGE=/boot/vmlinuz-6.8.7-1-default splash=0", will be passed to user space.

I have included the '/etc/default/grub' file below. The file has *different* entries, especially in the in it compared to the entries displayed in the log above.
Thinkcentre-M57p:~> cat /etc/default/grub
# If you change this file, run 'grub2-mkconfig -o /boot/grub2/grub.cfg' afterwards to update # /boot/grub2/grub.cfg.

How serious are these errors and can they be fixed and how? I think you can ignore that error. I have been seeing it for years.
It means that the line contains parts that are not listed as kernel parameters, are are passed on untouched to another part of the kernel boot processing, or rather the non kernel part of the boot process.
I get similar:
Apr 18 13:22:18 Telcontar kernel: Kernel command line: BOOT_IMAGE=/vmlinuz-5.14.21-150500.55.52-default root=UUID=ac173013-18ad-4c4e-921e-fd2ecfb56495 resume=/dev/disk/by-label/nvme-swap splash=verbose verbose Apr 18 13:22:18 Telcontar kernel: Unknown kernel command line parameters "verbose BOOT_IMAGE=/vmlinuz-5.14.21-150500.55.52-default splash=verbose", will be passed to user space.
Ok, thanks for your response on this situation.
