Ubuntu 20.04 Kernel Update Causes System Outages for Docker Users

If you spent the early days of June fighting kernel panics in Ubuntu 20.04, you were not alone – and we now know why.

A problem with a Ubuntu-specific Linux kernel patch early last month rendered many systems, running Docker on that flavor of the operating system unusable, and it probably won't be the last time.

The whole debacle can be traced back to a bad distro-specific kernel update for Ubuntu 20.04 — Canonical's long-term support (LTS) release — that started rolling out on or about June 8. Within hours of the patch hitting systems, bug reports began filing in.
