[SOLVED] kernel-desktop-latest-3.19.0-2.mga5 no img

[bertaerts]

I just installed the updates to Mageia 5 beta 3.

PC does not boot anymore, at least not with the new kernel.
Fortunately, the old kernel still works fine

This is how /boot looks like:

The .img file is missing for the new kernel 3.19.0-2.
Can I repair this myself?

[martinw]

Try this (as root):

Code: Select all

/bin/dracut -f /boot/initrd-3.19.0-desktop-2.mga5.img 3.19.0-desktop-2.mga5


[bertaerts]

Thanks. One step further, I now have .img:

But still in advanced options, selecting the new kernel does not boot, and I am not fast enough to see an error message.

[doktor5000]

What do you see if it boots?

[bertaerts]

Normally there is a message about ram disk in a smaller black window than the screensize.
With the new kernel, this window comes, but I don't see ramdisk or anything else appearing.
Then the screen becomes black and the disk activity is very slowly on: 0.5 sec on, 1 sec off and so on.
Not the normal disk activity.
Should I wait longer than a few minutes?

I use uefi grub2...

[doktor5000]

Should I wait longer than a few minutes?

Why not let it sit there for say 10 or 15 minutes - grab yourself a book or a beer in the meantime, whatever you prefer ...

[bertaerts]

Waited 15 minutes.
Only hard poweroff by pressing 5 seconds on the power button got the PC out of this state...

[doktor5000]

From one of the older kernels, you could still do

Code: Select all

urpmi --replacepkgs --replacefiles kernel-desktop-latest-3.19.0-2.mga5

to reinstall. Or

Code: Select all

urpme kernel-desktop-latest-3.19.0-2.mga5; urpmi kernel-desktop-latest-3.19.0-2.mga5

[bertaerts]

I think the issue is in /boot/grub2/grub.cfg

                initrd  /boot/initrd-3.19.0-desktop-1.mga5.img
        }


In the working kernel there is root=UUID=af743c5f-93f8-4b43-89f8-b7725fc63605.
In the non-working kernel there is root=/dev/sdd2
This file is auto-generated.
How do I generate it correctly?

I have had ALWAYS issues with kernel updates on Mageia 4 also when the OS is installed on an external USB disk.
With Mageia 4 I could solve it myself in grub configuration.
So here again Mageia 5 beta 3 is installed on an external USB disk...

[bertaerts]

When comparing both grub2 menu entries, a more important difference can be discovered.

Code: Select all

                    echo    'Loading initial ramdisk ...'
                    initrd  /boot/initrd-3.19.0-desktop-1.mga5.img


These 2 lines are missing in the menu entry for 3.19.0-desktop-2 !!!!

Can I edit this file /boot/grub2/grub.cfg?
Will it remain valid until the next kernel update?
When I run grub2-mkconfig, I get exactly the same file containing the error.
What is the input of grub2-mkconfig?

[niumao]

you can edit the menuentry in your grub.cfg as such

Code: Select all

menuentry 'Mageia, with Linux 3.19.0-desktop-2.mga5' --class mageia --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-3.19.0-desktop-2.mga5-advanced-af743c5f-93f8-4b43-89f8-b7725fc63605' {
                set gfxpayload=text
                insmod gzio
                insmod part_gpt
                insmod ext2
                set root='hd3,gpt2'
                if [ x$feature_platform_search_hint = xy ]; then
                  search --no-floppy --fs-uuid --set=root --hint-bios=hd3,gpt2 --hint-efi=hd3,gpt2 --hint-baremetal=ahci3,gpt2  af743c5f-93f8-4b43-89f8-b7725fc63605
                else
                  search --no-floppy --fs-uuid --set=root af743c5f-93f8-4b43-89f8-b7725fc63605
                fi
                echo    'Loading Linux 3.19.0-desktop-2.mga5 ...'
                linux   /boot/vmlinuz-3.19.0-desktop-2.mga5 root==UUID=af743c5f-93f8-4b43-89f8-b7725fc63605 rw
                echo    'Loading initial ramdisk ...'
                initrd  /boot/initrd-3.19.0-desktop-2.mga5.img
 }

[gohlip]

Obviously, your initrd line is missing.

Can you get this back by

Code: Select all

# dracut -f
# grub2-mkconfig -o /boot/grub2/grub.cfg

2 points
o your grub menu shows

Code: Select all

linux   /boot/vmlinuz-3.19.0-desktop-1.mga5 .......
initrd  /boot/initrd-3.19.0-desktop-1.mga5.img

instead of

Code: Select all

linux   /boot/vmlinuz-desktop ..........
initrd   /boot/initrd-desktop.img


o You have "net.ifnames=0" in your linux line.
Do you still need this with newer systemd?
Did you manually modify your grub.cfg?

[bertaerts]

What I did now:

Code: Select all

dracut -f --fstab /boot/initrd-3.19.0-desktop-2.mga5.img 3.19.0-desktop-2.mga5
grub2-mkconfig -o /boot/grub2/grub.cfg


Now my grub.cfg looks fine for all three kernels:

Code: Select all

Generating grub configuration file ...
Found theme: /boot/grub2/themes/maggy/theme.txt
Found linux image: /boot/vmlinuz-desktop
Found initrd image: /boot/initrd-desktop.img
Found linux image: /boot/vmlinuz-3.19.0-desktop-2.mga5
Found initrd image: /boot/initrd-3.19.0-desktop-2.mga5.img
Found linux image: /boot/vmlinuz-3.19.0-desktop-1.mga5
Found initrd image: /boot/initrd-3.19.0-desktop-1.mga5.img
Found Mageia 4 (4) on /dev/sda1
done

And I am now running 3.19.0-desktop-2.mga5

gohlip, to answer your two points:
1. there are 3 menuentries, also the one you mention, which are symbolic links to the latest kernel, I only showed the "numbered" ones.
2. commercial apps like Matlab from the Mathworks and Mathematica from Wolfram, still require eth0 for their license.
What I did was:

Code: Select all

su
emacs /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT= add "net.ifnames=0" to end of string
save and close emacs
update-grub2

[gohlip]

Good all is well.
Thanks for the explanations for the points.
Cheers. Take care.
