Recover Kernel Panic - not syncing: Attempted to kill init! exitcode=0x0000000b

Troubleshooting

Creating a bug report/issue

I have searched the existing open and closed issues

Required Information

  • DietPi version | 9.0.2
  • Distro version | Debian 11.9
  • SBC model | RPi4
  • Power supply used | PoE
  • SD card used | SanDisk extreme

through some defective blocks on the SD card, I’m running into this kernel panic. Also moved everything to a new SD card, but maybe also the defective files :wink:

What’s the best way to recover/restore the system (without losing services and data). Didn’t find an image for 9.0.2 anymore.

Thanks a lot,
best,
meg

how has this been done?

Do you have a backup of the system?

We don’t keep old images.

3

first dd. Then backup image restore. If I remember correctly, there were just some kb of non readable data.

None before the issues starts.

Guess it’s just one (important) broken file. Kernel panic coming directly after the init of the usb bus.

Can I do some kind of inplace Upgrade?

I’ve chrooted into the system:

No it feels somehow like this issue.

I rather think that more is broken than just a file. It seems to be quite a lot because of:

Have you already tried a file system repair?

> /forcefsck
reboot
# then after reboot
journalctl -t systemd-fsck

:cold_sweat:

Maybe it’s just cause of the chroot environment?

Jep. Boot and root. Kernel panic at the same point.

tried to rebuild the kernel image, but seems initramfs-tools aren’t installed.

sudo apt install --reinstall raspberrypi-kernel also not solve it :frowning: - beside most operations within the chroot environment running into some issues

As said, there is more file system corruption on your system. Not just one or two files.

Rodger that… how to fix/repair it?

My plan was to get the original image and binary compare files… but cause there is no original image … I opened this thread.
