Linux Kernel 4.15 is end-of-life. Greg Kroah-Hartman, a linux kernel
maintainer, said that all users of the 4.15 kernel series must upgrade.
Is there any timeline ugrading 4.16 kernel to Proxmox?

>> There was no kernel panic... While rebooting the kernel crashed, you can find the screenshots at: https://privatebin.at/?450815b1e2b6977f#OZF5/DEC8pwJHM8NVMR0/ODogOPS3U1o738Riz813F4= [1] https://privatebin.at/?37d273119ba7acf4#YeJY6Y3K52vQPrncUvBfe+Ah8rzS+FD+6arkQHlRxAI= [2] I booted the old kernel 4.13.16-2-pve without problems. Specs: 3 node cluster with ceph. Supermicro SYS-1029U-TR4T 2x Intel Xeon Silver 4108 1,8 GHz Box Sockel 3647 64 GB DDR4 Btw. live migration from older kernel seams to fail too, but that hasn't been tested much.
