Hi All! I have SLE 15 SP3 SAP that cannot boot due to the error end kernel panic - not syncing: No working init found. Try passing init= option to kernel.
This happened after my zypper update online in SLE 15 SP3. I run offline upgrade from SLES 12 SP5 to SLE 15 SP3 successful but the yast and other apps is not updated so i run the zypper update online and apply the updates. After reboot it can’t boot now.
Appreciate your thoughts about this. Thanks in advance for helping me!
@M_A_T Hi and welcome to the Forum 
It’s running btrfs and snapshots, so should be able to select a previous snapshot to boot from?
@M_A_T so when it boot’s at the GRUB menu, select advanced and should off to select a snapshot to boot from?
@M_A_T Almost sounds like grub wasn’t installed properly… Have a read here https://www.suse.com/support/kb/doc/?id=000019909
Or has /boot filled up?
Yes @malcolmlewis1 i successfully shim-install
Also have problem when dracut or mkinitrd cannot proceed due to initrd missing
@malcolmlewis1 dracut module ‘initrd’ cannot be found same. Run commands: mkinitrd and dracut -f --regenerate-all
@M_A_T So /boot is not full? Your also booting from 000A, can you run efibootmgr -n 000B and then reboot, the -n just sets a one off boot from that entry. Also check the output from efibootmgr -v and make sure the entries all look ok.
@M_A_T See how the two different entries point to two different locations on /boot/efi/EFI do the shim.efi files exist in this location?
Do you have an option to reboot this system?
will set back efibootmgr -n 000A, for a while will reboot the server.
