Hi,
Same problem here, on Odroid HC2, having Armbian Linux 4.14.141-odroidxu4 and yesterday run apt upgrade unsuspectingly.
Upgraded to Linux 4.14.144-odroidxu4 kernel.
After that system was not available for ping and SSH. Multiple hard reboots does not solve, sometimes system was available, but always frozen after a few seconds.
Solution:
I had an old /boot backup and i copied to the boot SD card, the four major kernel boot files:
initrd.img-4.14.69-odroidxu4, vmlinuz-4.14.69-odroidxu4, System.map-4.14.69-odroidxu4, config-4.14.69-odroidxu4 ),
and one directory:
dtb-4.14.69-odroidxu4
then create simlink to dtb, uInitrd, zImage
rebooted and finger crossed, and hope ssh would work... and thanks Linus it had been worked.
