Grub bug?

I get the following when I run:

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

My web search got me: https://savannah.gnu.org/bugs/?func=det … em_id=8539
But bug seems quite old....

Not sure what to make of it...  Any ideas what could be going on?
I haven't rebooted yet.

Edit: I rebooted and updated 'grub.cfg' and:

Now grub is creating double entries. I guess this is a known issue.

And disabling 10_Linux doesn't seem like an option as I have other distros in the picture.

Any ideas how to go about it?

Regards....

Re: Grub bug?

The only thing that comes to mind is that you possibly have updated recently without rebooting.  So it is trying to use device-mapper (the dm_mod kernel module), but the update has replcaed the old set of modules with the new ones, and it isn't available.

If that isn't it, I have no idea.  I am not much of a grub user (I use it to boot the archiso in a loopback with UEFI), so I don't think I can comment further unless a lot more information is provided.

Re: Grub bug?

1. Downgrade to the same kernel version that `uname -a` states you are using. pacman -U /var/cache/pacman/pkg/linux-xxx.pkg.tar.xz
2. Run `grub-mkconfig -o /boot/grub/grub.cfg`
3. Install the newest kernel `pacman -S linux`

Re: Grub bug?

I have the sam problem but i'm on the same kernel that uname -a shows. Is there a way to fix it? I won't change kernel because i have the one that was used. This thing comes after installing intel-ucode package for update intel ucode. It just stops at the
