[SOLVED] kernel panic, failed to execute /init

Tried:
1) Reinstalling kernels, mkinitcpio.
2) Files are there.

Happens with all installed kernels(ck, latest and lts).

Ideas?

Edit: What happend here?
1) Gnucash 3.03 update had a conflicting files error. I forced the installation which deleted the /usr/lib64 link.
2) init could not be loaded.
3) I had to restore the link in arch-chroot and reinstall every package that was installed or updated after this forced update

ln -s /lib /usr/lib64

The list of packages can be found in pacman log (/var/log/pacman.log)
4) Since I reinstalled /boot, I also had to change it's UUID in fstab.

Bottom line: Don't use --force just like that. And if used write it down on paper and reboot after to see everything is ok.

Re: [SOLVED] kernel panic, failed to execute /init

What does "files are there" mean? Are sure they are there? Do you use UEFI and are certain that the ESP partitiion was mounted to /boot during the update/reinstall and that you are not accidentally looking at the /boot directory that isn't hooked up to the ESP? And that you have enough space left on the ESP? Details of your partition setup?

Re: [SOLVED] kernel panic, failed to execute /init

The esp is boot dir.
the EFI is there.

partitions:
sda1: boot. 250mb of 500mb are used
sda2 : root 20gb free

To clarify: I installed the esp into the boot partition

Please post the output of `ls -la /boot`, provide all the relevant details on your bootloader and read the CoC and replace your screenshot with a thumbnail / link.

Is using systemd-boot the only fact you consider relevant regarding your bootloader setup? If yes, then think about to what extent a person can help you given only that piece of information.

Obviously I meant that you should also provide all configuration files (please make sure to read the wiki and include all the mentioned configuration files of systemd-boot). And while you're at it, also post the output of `lsblk -f -o +UUID`.

Re: [SOLVED] kernel panic, failed to execute /init

# vim:set ft=sh
# MODULES
# The following modules are loaded before any boot hooks are
# run.  Advanced users may wish to specify all system modules
# in this array.  For instance:
#     MODULES="piix ide_disk reiserfs"
MODULES="bcache"

# BINARIES
# This setting includes any additional binaries a given user may
# wish into the CPIO image.  This is run last, so it may be used to
# override the actual binaries included by a given hook
# BINARIES are dependency parsed, so you may safely ignore libraries
BINARIES=""

# FILES
# This setting is similar to BINARIES above, however, files are added
# as-is and are not parsed in any way.  This is useful for config files.
FILES=""

# HOOKS
# This is the most important setting in this file.  The HOOKS control the
# modules and scripts added to the image, and what happens at boot time.
# Order is important, and it is recommended that you do not change the
# order in which HOOKS are added.  Run 'mkinitcpio -H <hook name>' for
# help on a given hook.
# 'base' is _required_ unless you know precisely what you are doing.
# 'udev' is _required_ in order to automatically load modules
# 'filesystems' is _required_ unless you specify your fs modules in MODULES
# Examples:
##   This setup specifies all modules in the MODULES setting above.
##   No raid, lvm2, or encrypted root is needed.
#    HOOKS="base"
#
##   This setup will autodetect all modules for your system and should
##   work as a sane default
#    HOOKS="base udev autodetect block filesystems"
#
##   This setup will generate a 'full' image which supports most systems.
##   No autodetection is done.
#    HOOKS="base udev block filesystems"
#
##   This setup assembles a pata mdadm array with an encrypted root FS.
##   Note: See 'mkinitcpio -H mdadm' for more information on raid devices.
#    HOOKS="base udev block mdadm encrypt filesystems"
#
##   This setup loads an lvm2 volume group on a usb device.
#    HOOKS="base udev block lvm2 filesystems"
#
##   NOTE: If you have /usr on a separate partition, you MUST include the
#    usr, fsck and shutdown hooks.
HOOKS="base udev autodetect modconf block bcache filesystems keyboard fsck"

# COMPRESSION
# Use this to compress the initramfs image. By default, gzip compression
# is used. Use 'cat' to create an uncompressed image.
#COMPRESSION="gzip"
#COMPRESSION="bzip2"
#COMPRESSION="lzma"
#COMPRESSION="xz"
#COMPRESSION="lzop"
#COMPRESSION="lz4"
COMPRESSION="cat"

# COMPRESSION_OPTIONS
# Additional options for the compressor
#COMPRESSION_OPTIONS=""

Also tried passing init path. same result.
robg: not the same problem ;(

The only related thing is that both /lib and /lb64 point to /usr/lib.
Is that ok?

Re: [SOLVED] kernel panic, failed to execute /init

Indeed, that's fine, and unfortunately does not resolve your issue. Nonetheless I believe that the theme is the same, some init-related files cannot be found and hence your boot fails. What does `pacman -Qkk systemd` say?

Re: [SOLVED] kernel panic, failed to execute /init

This is unlikely to be related to the problem, but when is the last time you merged your pacnew files? mkinitcpio has been using arrays instead of stings for ~6 months now. Either you haven't updated in that time, or you have been neglecting your pacnew files.

Re: [SOLVED] kernel panic, failed to execute /init

Please post the system's pacman.log particularly the update that included the kernel related to this issue onwards also the output of the following adjusted as needed if you use live media to access the system

bsdcpio -itF /boot/initramfs-linux.img

[2018-04-06 12:08] [PACMAN] Running 'pacman -U --force mkinitcpio-busybox-1.27.2-1-x86_64.pkg.tar.xz'

What was the reason for the force?
The following should extract the init from the initrd it should match /usr/lib/initcpio/init

bsdcpio -iF /boot/initramfs-linug.img init

Can you also check on the systems / parition that /bin and /sbin are links to /usr/bin and /usr/bin/init is a link to ../lib/systemd/systemd

That was done with chroot.

/usr/lib/initcpio/init  and  init have the same md5sum

If you add the option break=postmount are you dropped to a shell with the root filesystem of the system mounted at /new_root ?

Re: [SOLVED] kernel panic, failed to execute /init

Ok. I've restored /usr/lib64 link, installed all the packages that were updated since that mistake and now It'll boot. But it can't access one of the disk so  get emergency shell. I know the disk uuid but I can't find it with fdisk. It's the /boot partition. And since I reinstalled it, it has a new uuid which I forgot to change in fstab...

That's the system log:
