'Unknown kernel command line parameters '

RandomTroll · 10-24-2023, 01:56 PM

Beginning today, when I boot I get:

Quote:

Kernel command line: auto BOOT_IMAGE=Linux-6.5.8 ro root=801 vt.default_utf8=0
Unknown kernel command line parameters "auto BOOT_IMAGE=Linux-6.5.8", will be passed to user space.

The word 'auto' appears nowhere in lilo.conf or allied files. I've rebuilt and reinstalled the kernel. It doesn't seem to cause a problem. Slackware, lilo

Apparently the 'Kernel command line:' only gets displayed if there's a problem; it hasn't happened before.

I think it may be happening to everybody using more recent kernels:

Code:

# grep RETT /etc/os-release
PRETTY_NAME="openSUSE Tumbleweed"
# uname -r
6.4.12-1-default
# dmesg | grep -i unknown
[    0.021889] Unknown kernel command line parameters "BOOT_IMAGE=/boot/vmlinuz", will be passed to user space.

Years ago already I started seeing BOOT_IMAGE= show up in Mageia's Grub stanzas, but only recently have I noticed it showing up as you noticed without its presence in Grub stanzas.

Although it started happening only yesterday I was checking only that month's logs. A search through my archives found it has happened randomly in the past. How can it object to the 'BOOT_IMAGE' parameter? Isn't that necessary? I think the parameter isn't the problem, the whoever is checking has made a mistake. It doesn't show up in my dmesg.

Code:

cat /proc/cmdline
