Getting a new kernel to boot

Wed · 02-04-2024, 06:08 PM

Still a continuation from my elilo woes. I think I'm nearly there. However I stumble on the finish line.

At reboot, the new kernel (5.15.145) couldn't find its modules. Right now, the system is up with the USB boot stick, so I can connect to it over the network.

I temporarily recommented the kernel entries in the blacklist and downloaded the kernel packages.

Code:

# cd /var/cache/packages/patches/packages/linux-5.15.145/
# installpkg kernel-headers-5.15.145-x86-1.txz
# cd ..
# upgradepkg kernel-firmware-20231222_a7dee43-noarch-1.txz

Yes I ran installpkg on all the kernel packages.

Code:

# cd /boot
# cp vmlinuz-generic-5.15.145 efi/EFI/Slackware/
# cp vmlinuz-huge-5.15.145 efi/EFI/Slackware/

Code:

# /usr/share/mkinitrd/mkinitrd_command_generator.sh -k 5.15.145
# mkinitrd -c -k 5.15.145 -f ext4 -r /dev/nvme0n1p3 -m xhci-pci:ohci-pci:ehci-pci:xhci-hcd:uhci-hcd:ehci-hcd:hid:usbhid:i2c-hid:hid_generic:hid-asus:hid-cherry:hid-logitech:hid-logitech-dj:hid-logitech-hidpp:hid-lenovo:hid-microsoft:hid_multitouch:jbd2:mbcache:crc32c_intel:crc32c_generic:ext4 -u -o /boot/initrd-5.15.145.gz
# cp initrd-5.15.145.gz efi/EFI/Slackware/

I added the version to the output file.

Code:

# ls /boot

initrd-5.15.145.gz*

vmlinuz*
vmlinuz-generic-5.15.145*
vmlinuz-huge-5.15.145*

I figured a pure copy of the first entry would do, but add the version number as I had generated them earlier.

Code:

# nano elilo.conf 

chooser=simple
delay=1
timeout=1
#
image=vmlinuz
	label=vmlinuz
        initrd=initrd.gz
        read-only
        append="root=/dev/nvme0n1p3 vga=normal ro"

image=vmlinuz-5.15.145
        label=vmlinuz-5.15.145
        initrd=initrd-5.15.145.gz
        read-only
        append="root=/dev/nvme0n1p3 vga=normal ro"

Is there anything simple I missed, or screwed up? A space or , in the wrong spot? Something I can do to make my system bootable?

You don't have vmlinuz-5.15.145 in the efi directory.

Did you install the kernel-modules-5.15.145 package?

In your code post /efi/EFI/Slackware , you have the symbol * after every file, which isn't in your elilo.conf.

try removing the *'s.

For your reference here is my elilo.conf

Code:

chooser=simple
prompt
timeout=50
default=flop
#
image=vmlinuz-generic-5.15.117
        label=ops
        initrd=initrd.gz
        read-only
        append="root=/dev/sda2"  
 
image=vmlinuz-huge-5.15.117
        label=flop
        initrd=initrd.gz
        read-only
        append="root=/dev/sda2 vga=normal ro"

Yes I know I am not using the current kernel. And I have ro -read only- repeats. But since typing either "ops" or "flop" boots I am too much of a slacker to fix it.
