[SOLVED] Kernel panic - not syncing: No working init found. Please help!

kgha · 11-04-2023, 12:32 PM

Don't know if something went wrong with latest -current upgrades or what, but when rebooting I run into kernel panic.

Don't know why boot process can't find a working init, /sbin/init is there.

Grateful for help to fix this without a complete reinstall, if possible.

Can you reload into the previous kernel?
And a screenshot of the error if you could too.

Here the new 6.1.61 generic kernel plus initrd works just fine.

kgha · 11-04-2023, 12:54 PM

My lilo setup lets me choose between generic, huge, and previous kernel (6.1.60), but I get kernel panic for all 3. "Screenshot" (photo) attached.

Do you have a Slackware Live USB stick lying around? Just to rule out a hardware failure?

kgha · 11-04-2023, 01:09 PM

Yes, I have a recent liveslak stick and can boot from that.

Tried to chroot into the faulty system, but:

bash-5.2# mount /dev/sda1 /mnt
bash-5.2# mount -o bind /dev /mnt/dev
bash-5.2# mount -o bind /proc /mnt/proc
bash-5.2# mount -o bind /sys /mnt/sys
bash-5.2# chroot /mnt /bin/bash
chroot: failed to run command ‘/bin/bash’: No such file or directory

What does lsblk tell you? (Just to make sure /dev/sda1 is not on the usb stick now.)

Now that you mounted it to /mnt, if you cd /mnt and use ls -l, do you see the usual stuff there (bin, home etc) ?

From the live usb, can you see the hdd and partitions on the HP Elitebook and list them?

Windu · 11-04-2023, 01:23 PM

Did you perform that upgrade using a repository for the wrong architecture? I.e. 32bit packages to replace the older 64bit packages. Try "file" command on a couple of binaries, assuming that the files are still there but just can't execute.

Upgrades were from the proper repo (64bit)

Code:

mount /dev/sda1 /mnt
  mount --bind /dev /mnt/dev
  mount --bind /tmp /mnt/tmp
  mount --bind /run /mnt/run
  mount -t proc proc /mnt/proc
  mount -t sysfs none /mnt/sys
  mount -t devpts -o noexec,nosuid,gid=tty,mode=0620 devpts /mnt/dev/pts
  chroot /mnt /bin/bash

if fails try

Code:

exit
umount /mnt
fsck -f /dev/sda1

/dev/sda1 is indeed the / partition of my SDD, so that's as it should be. And the outcone of cd /mnt + ls -l looks OK:

There is something wrong here. You say it's 64bit, but you don't have /lib64 directory?

You're right, Petri - now how the hell could that directory disappear? And how can I replace it? Copy from my USB?

kgha · 11-04-2023, 02:17 PM

Hmm, when looking at the content of /lib and /lib64, it is as if they have been merged somehow... lots of stuff in /mnt/lib that on my USB stick resides in /lib64.
