[SOLVED] Kernel command line not saved by [update-initramfs]

Hello:

Up until today, my kernel command line was this one:

acpi_osi=Linux intel_pstate=disable pci=noaer reboot=pci,force numa=off security=0 apparmor=0 nmi_watchdog=0 tsc=nowatchdog agp=off ipv6.disable=1 enable_mtrr_cleanup=1

As I am still searching for a solution for a bad shutdown I have with my Sun Ultra 24 WS, I added [igb.EEE=0] to the kernel command line ...

acpi_osi=Linux intel_pstate=disable igb.EEE=0 pci=noaer reboot=pci,force numa=off security=0 apparmor=0 nmi_watchdog=0 tsc=nowatchdog agp=off ipv6.disable=1 enable_mtrr_cleanup=1

... and then did the usual [update-initramfs -u], shut down and then rebooted the box.

But for whatever reason (no idea, never seen this before) the kernel command line in the [dmesg] printout does not include the addition:

[    0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-6.1.0-52-amd64 root=UUID=d6841f29-e39b-4c87-9c52-3a9c3bafe2d3 ro acpi_osi=Linux intel_pstate=disable pci=noaer reboot=pci,force numa=off security=0 apparmor=0 nmi_watchdog=0 tsc=nowatchdog agp=off ipv6.disable=1 enable_mtrr_cleanup=1

Can anyone tell me what is happening?
The only difference I have noticed is that [update-initramfs -u] takes a bit longer than usual.

Do not think it is the character count -> there are 258 characters and IIRC the limit is 1MB (?)
What is tampering with my [igb.EEE=0] stanza?

Best,

A.

When you use grub, edit /etc/default/grub to add the new parameter, perform an

# update-grub

That should do the job.

Re: [SOLVED] Kernel command line not saved by [update-initramfs]

Hello:

When you use grub, edit /etc/default/grub to ...

Right ...   8^°

Just why did I get tangled up in/with [update-initramfs] when I should have been doing [update-grub]?
What a DH ...

Thank you so much.

Best,

A.
