It's EOL for kernel.org, the highest kernel upstream. We base ours on
Ubuntu's 18.04 LTS, which will get support (i.e. bug (security and
others) fixes, new hardware support, etc. until 2023 (new hardware
"only" until 2020, though) by Ubuntu's and our kernel people.
So that's not a problem. We'll keep the 4.15 kernel through the
remaining lifetime of PVE 5.X, which will be EOL'ed probably someday in
2020, if I had to guess .

While rebooting the kernel crashed, you can find the screenshots at: https://privatebin.at/?450815b1e2b6977f#OZF5/DEC8pwJHM8NVMR0/ODogOPS3U1o738Riz813F4=  https://privatebin.at/?37d273119ba7acf4#YeJY6Y3K52vQPrncUvBfe+Ah8rzS+FD+6arkQHlRxAI=  I booted the old kernel 4.13.16-2-pve without problems.
