[SOLVED] systemd-boot - kernel line parameters garbage

GeorgeJP · 2022-11-11 19:24:31

I am using systemd-boot with unified kernel image /boot/EFI/Linux/archlinux.efi,
created by mkinitcpio preset:

ALL_config="/etc/mkinitcpio.conf"
ALL_kver="/boot/vmlinuz-linux"
ALL_microcode=(/boot/amd-ucode.img)
PRESETS=('default')
default_image="/boot/initramfs-linux.img"
default_efi_image="/boot/EFI/Linux/archlinux.efi"
default_options="--splash /usr/share/systemd/bootctl/splash-arch.bmp"

After systemd update to 252.1 when I boot this image I get this in journal:

root@lnb ~ $ journalctl -b 
lis 11 19:56:09 lnb kernel: Linux version 6.0.8-arch1-1 (linux@archlinux) (gcc (GCC) 12.2.0, GNU ld (GNU Binutils) 2.39.0) #1 SMP P>
lis 11 19:56:09 lnb kernel: [500B blob data]
lis 11 19:56:09 lnb kernel: [Firmware Info]: CPU: Re-enabling disabled Topology Extensions Support.

(blob data instead of kernel parameters)
I did check:

jp@lnb ~ $ cat /proc/cmdline 
root=LABEL=ARCHFS tsc=unstable trace_clock=local rw 8250.nr_uarts=1 loglevel=3 m~o}V9}߿?{^7_oo~wϯߚmZۿ-)k_~o?zwۼow7vb{=?|m{3~_o~^߿~}?~ǿϯ[?o_}<W{?߽~{w}?omO?~?~'w{mw?o_?wo~W~_3y?}}owǆ?o?ߟ}o?~}?}׾_oSmw߭_ww{ߍy㿛ϧ;}]o{稷ww_{?7˟Oſws??~?e?{_ۿϵvߞ_^o_}8m{??;^wSןooz?\}d?o>۪׵___z?|:].~ݻ/o~ݾ͗+}}~uw?gUO{{o[}~wu]_

When I boot "standard" way, using arch.conf:

root@lnb ~ $ cat /boot/loader/entries/arch1.conf
title Arch Linux
version manual entry
linux /vmlinuz-linux
initrd /amd-ucode.img
initrd /initramfs-linux.img
options root=LABEL=ARCHFS notsc rw 8250.nr_uarts=1 fsck.mode=force fsck.repair=yes loglevel=3

it boots without errors

root@lnb ~ $ journalctl -b -1
lis 11 19:54:09 lnb kernel: Linux version 6.0.8-arch1-1 (linux@archlinux) (gcc (GCC) 12.2.0, GNU ld (GNU Binutils) 2.39.0) #1 SMP PREEMPT_DYNAMIC Thu, 10 Nov 2022 21:14:24 +0000
lis 11 19:54:09 lnb kernel: Command line: initrd=\amd-ucode.img initrd=\initramfs-linux.img root=LABEL=ARCHFS notsc rw 8250.nr_uarts=1 fsck.mode=force fsck.repair=yes loglevel=3
lis 11 19:54:09 lnb kernel: [Firmware Info]: CPU: Re-enabling disabled Topology Extensions Support.

Is this upstream bug or is it bug in mkinitcpio?

Edit: image creation

jp@lnb /etc/kernel $ sudo mkinitcpio -P

  -> -k /boot/vmlinuz-linux -c /etc/mkinitcpio.conf -U /boot/EFI/Linux/archlinux.efi -g /boot/initramfs-linux.img --splash /usr/share/systemd/bootctl/splash-arch.bmp --microcode /boot/amd-ucode.img

Edit2: If unified image created manually, commandline looks ok
https://wiki.archlinux.org/title/Unifie … e#Manually

Edit3: If unified image created with sbctl, commandline looks ok
https://wiki.archlinux.org/title/Unifie … mage#sbctl

... so problem is in mkinitcpio (I think)

I'm assuming that is from the journal and not from /proc/cmdline? Whichever it is, what does the other one say?

Thank you

Edit: resolved upstream in systemd 252.2-2
