LinuxQuestions.org - When upgrading to kernel 5.15.80 unable to boot

Law I don't know where you missed a post of this type, hahaha, well here you have it.

I've been trying since kernel 5.15.80 came out and no matter what I do I can't do it in any way, I'm going to explain in detail the steps I take to see where the error is, because no matter how hard I try I can't:

I use slackware xfce 64 bit, I was using it, with zero problems, with the generic 5.15.63 kernel and upgrading to the new kernel is where it all starts.

slackpkg update
slackpkg upgrade-all

The kernel updates appear, I accept them, when everything is finished:

I follow the steps described here for the generic kernel:

http://docs.slackware.com/es:slackwa...ackware_system

But in the part that says the kernel, I put the 5.15.80

later:

cp /boot/vmlinuz-generic-5.15.80 /boot/efi/EFI/
cp /boot/vmlinuz-generic /boot/efi/EFI/
cp /boot/initrd.gz /boot/efi/EFI/

Then I do the following in grub:

I edit the grub:

nano /boot/grub/grub.cfg

I copy everything.

Later:

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

I edit the grub again:

nano /boot/grub/grub.cfg

I delete everything and paste the grub that I copied earlier, but changing the entries that say 5.15.63, for 5.15.80

And then I restart the computer and when I restart, I always find what it says in the image that I attached and there is no way to start slackware. Windows boots and linux mint boots, but not slackware.

I have a rescuezilla image, with which I can leave the system as it was with the generic kernel 5.15.63, but I haven't restored it at the moment, in case I had a solution with a live cd.

If you wish, I can restore the image and we will go step by step to see if we succeed or if you see that it is better with a livecd, whatever you see is better.

Thanks for everything. Greetings.
