Loading Linux linux ...Forever and Kernel Panic

Since last sunday I'm experiencing exactly the same issue as post: . But, after doing the indicated steps but many in this awesome forum little has changed. So I'm doing something really bad!. So thank you in advance to any help.

First, this is a machine I use for downloading and file server with samba, so of course I can wipe out the partition and re-install again for for educating purposed I want to solved this out.
The problem appear last week doing an unattended pacman installation of several software packages (yes I know, a bad idea!).

The simptons is that on screen after grub initial choice:

Loading Linux linux ...

...and this hangs forever....

So what I did is edited the grub menu and eliminate 'quiet' and increase the verbose level. I obtained a KERNEL panic - not syncing: VFS: Unable to mount root on unlock(0,0)
No matter what I do with a new arch ISO this situation doesn't change. Please see below and image that shows the kernel panic code.

To summarize what I did so far with the 1st of august ISO (which has kernel 5.7.11)

I re-installed grub from arch iso and a summary of what I did is this:

Mount the /dev/sda1
arch-chroot that mount and then:

    rm /var/lib/pacman/db.lck
    pacman -Syyu
    pacman -S grub linux mkinitcpio

    Then I regenerate initramfs using:

    mkinitcpio -p linux

    and since I use grub in that specific mobo I use:

    grub-mkconfig -o /boot/grub/grub.cfg

    grub-install --target=i386-pc /dev/sda

    And the I restart.

I want to stress out that I did the above in different reboots. And pacman installed a new updated kernel, now  5.7.12 as you can see in the image. Nevertheless /boot directory contains the kernel (vmlinuz-linux) and the initramfs.img file image.

/etc/default/grub is unedited, and running grub-install completes w/o errors

For that please see the next image:

Any help is really appreciated!

Re: Loading Linux linux ...Forever and Kernel Panic

Please post the full contents of /boot/grub/grub.cfg as text see the tip box from pastebin to post from the console directly to a pastebin.
Also the output of

# blkid
# parted -l

Re: Loading Linux linux ...Forever and Kernel Panic

Thank you loqs for your prompt answer. The funny thing here is that /boot/grub/grub.cfg doesn't exits. The whole directory grub is non existent.

I can't boot....so how to issue those commands?

regards.

Re: Loading Linux linux ...Forever and Kernel Panic

Execute the commands from the installation media.  Also from the installation media mount the system's filesystems to /mnt as you did during installation.  Then what is the output of

findmnt /mnt
find /mnt/boot

Great, these are the outputs:

...then parted shows me another hard disk on /dev/sdb

UUID are fine, in this case SDA has UUID as "9bdec9ed-7379-4d8c-90cf-40666c415190" and everything points to SDA1 where the active partition resides and not the other hard drive (SDB) that does no have a boot partition or a root filesystem.

If for some reason on your installed environment gets initialized the other way around, it does not matter that sdb has no boot partition, it will still try to mount /dev/sda1, even it it is what is sdb1 on the live disk.

try replacing

linux	/boot/vmlinuz-linux root=/dev/sda1 rw acpi_enforce_resources=lax loglevel=3 quiet

with

linux	/boot/vmlinuz-linux root=UUID=9bdecSed-7373-4d8c-90cf-40666c415190 rw acpi_enforce_resources=lax loglevel=3 quiet

Re: Loading Linux linux ...Forever and Kernel Panic

Actually, the problem might be a missing initrd entry. You said you have run

mkinitcpio -p linux

but your grub.cfg is missing:

[cfg]
        initrd    /boot/initramfs-linux.img
[/cfg]

Try adding these after the kernel like that I just asked you to replace. Also check if /boot/initramfs-linux.img exists.

Re: Loading Linux linux ...Forever and Kernel Panic

Thank you metabuble...I'm on my way of performing these actions...

But the first striking thing is that:

/boot/initramfs-linux.img does NOT exists.

but what we have is

/boot/initramfs.img

as I pointed out in my first post.

Somehow, mkinitcpio ouputs initramfs.img and does not rename it?

Re: Loading Linux linux ...Forever and Kernel Panic

What's in /etc/mkinitcpio.d/ ?

Re: Loading Linux linux ...Forever and Kernel Panic

Ok

So adding:
linux    /boot/vmlinuz-linux root=UUID=9bdecSed-7373-4d8c-90cf-40666c415190 rw acpi_enforce_resources=lax loglevel=4

...did not help, exactly the same behavior. We obtain a kernel panic.

Interestingly,  /etc/mkinitcpio.d directory has only a file called "linux.preset" which has no contents, a zero length file.

Re: Loading Linux linux ...Forever and Kernel Panic

That's your problem. Delete it and reinstall the kernel package.

Re: Loading Linux linux ...Forever and Kernel Panic

Thank you Scimmia

You mean install the 'linux-lts' or the simply the 'linux' pacman package. I'm in doubt because I already did that in the order posted in my first post.

Re: Loading Linux linux ...Forever and Kernel Panic

No you didn't. Notice I told you to do *two* things, not just reinstall the kernel.

No, sadly, the same Kernel Panic.

Re: Loading Linux linux ...Forever and Kernel Panic

So you have an initramfs now? And set the bootloader to use it?

Scimmia, what you mean with the bootloader? I did not touch it! I leave grub alone...

Re: Loading Linux linux ...Forever and Kernel Panic

Adding initrd command into grub.cfg did the job. The machine booted.

Now, a listing of kernel 5.7.12 in the grub directory is now:

$ ls -s
total 55600
    4 grub   9196 initramfs.img  29464 initramfs-linux-fallback.img   9648 initramfs-linux.img   7288 vmlinuz-linux

Still, I don't know why /etc/mkinitcpio.d was not deleted by the batch file 'mkinitcpio' when I proceed with:

mkinitcpio -p linux

Re: Loading Linux linux ...Forever and Kernel Panic

Will this create the proper initramfs files?

mkinitcpio -P

Don't forget to create a new grub config with proper initramfs entries

grub-mkconfig -o /boot/grub/grub.cfg

Re: Loading Linux linux ...Forever and Kernel Panic

Sorry for the delay in replaying.

Indeed metabubble,

mkinitcpio -P linux

creates the initramfs files.

but

mkinitcpio -P

does not.
