[SOLVED] Slackware 14.2 huge kernel Panic

linuxxer · 02-12-2018, 06:14 AM

Slacker,

Few days back I have updated my system (Slackware 14.2).
When I tried to boot with huge kernel it gives me error.

Please check the attachment for error.

I am able to boot with generic kernel with initrd.gz without any problem.

Please suggest....

are you sure it's pointing to huge kernel? Looking from the error message, it was unable to mount your root partition due to missing kernel modules which should be included in the initrd

As per my understanding, huge kernel include all the drivers.
So I think no need of initrd.gz.

As per error message kernel get loaded, it means it is pointed to huge kernel.

Please suggest....

Yes, you are correct about the huge kernel.

But looking at the error message: Unable to mount root fs is a common sympthom that you probably use generic.

Thanks for your reply.

hi, maybe share your lilo configuration and listing of /boot and /lib/modules ?
there are a variety of vmlinuz files, your are most likely to need the smp one wmlinuz.*smp.

Code:

ls -alrt /boot | grep vmlinuz
vmlinuz-generic-smp-4.4.115-smp
vmlinuz-huge-smp-4.4.115-smp
vmlinuz-generic-4.4.115
vmlinuz-huge-4.4.115
vmlinuz-generic -> vmlinuz-generic-4.4.115
vmlinuz-generic-smp -> vmlinuz-generic-smp-4.4.115-smp
vmlinuz-huge -> vmlinuz-huge-4.4.115
vmlinuz-huge-smp -> vmlinuz-huge-smp-4.4.115-smp
vmlinuz -> vmlinuz-huge-smp-4.4.115-smp

https://docs.slackware.com/slackware:beginners_guide
when you created the initrd what was the command output generated ?

Code:

/usr/share/mkinitrd/mkinitrd_command_generator.sh

mkinitrd -c -k 4.4.115-smp

No, error message doesn't show which 4.4.115 kernel is loaded

unless you fixed it already,
if you shared specific files and directories content of your setup on which you encounter an issue w/ huge kernel that would help

As _peter mentioned, unless you've fixed it, additional information would be helpful.

I would suggest providing the output of ls -l /boot/ and /etc/lilo.conf to see if something stands out on causing your issue. If you need to boot off an installation "disk", you may need to mount the root drive and adjust the paths slightly for that mounted directory before providing the output.
