When upgrading from 4.15.0-39 to 4.15.0-42 on my Ubuntu 18.04.1 NAS
(x86_64) I get the following error on system bootup (freeze):
Failed to execute /init (error -2)
Kernel panic - not syncing: no working init found.
So apparently the init is broken.
My solution was to remove 4.15.0-42
sudo apt remove linux-image-4.15.0-42
sudo apt autoremove
and, thus, automatically go back to 4.15.0-39 which works fine.
The autoremove removed amd64-microcode, intel-microcode iucode-tool and
thermald which appear to be needed by -42 only.
