Releases: Ubuntu Server 16.04 and Ubuntu Server 18.04 2. Package: Linux Kernel 4.15.0-60 amd64 3. What I expected to happen: Not a recurrent kernel panic. 4. What happened instead: Recurrent kernel panic. While running Ubuntu 16.04 server on an internet appliance that was serving as my router, after the system was updated from kernel 4.15.0-58 to 4.15.0-60, I began getting frequent kernel panics (system seldom remained up for more than an hour after a reboot). I have included example stack traces below. After memtest revealed no problems, and fsck revealed no problems, I opted to rebuild from a fresh install, this time of Ubuntu 18.04, server. Upon completing the rebuilt, and put it back in service. It crashed with the same kernel panic within 30 minutes. I have since updated to kernel 5.0.0-27 and the kernel panics have completely stopped. [10170.296117] kernel BUG at /build/linux-5mCauq/linux-4.15.0/net/ipv4/ip_output.c:636!
