kernel panic on Ubuntu 20.04.4 LTS with kernel 5.13.0-1028-aws when using docker

3

On a freshly installed t3.micro instance with Ubuntu 20.04 and kernel 5.13.0-1028-aws, when I use docker (20.10.12-0ubuntu2~20.04.1), the kernel panics and the instance reboots. Downgrading to the previous kernel (5.13.0-1025-aws) solves the issue. Does anyone know where problems like this should be reported?

  • Just experienced this myself with the same kernel but with newer docker 20.10.17, build 100c701. There are several updates concerning some CVE to the kernel between 1025 and 1028 (e.g. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1968591), I suspected somethings broken along the way

  • t2.medium and t2.xlarge with Ubuntu20.04 with docker a problem for us too. Simply ran sudo apt upgrade and boom, it broke. Reboots and a few seconds after boot then kernel panic. Fresh instance with new 20.04LTS and apt upgrade breaks that too. Oops!

  • How can we downgrade to the previous kernel ?
