After upgrading Ubuntu 20.04 LTS to Ubuntu 22.04LTS, the server always freezes after ~10 minutes. All services are down, cannot ssh, connect to serial console but cannot input. However, this issue never happen before release upgrade.

升级Ubuntu 20.04 LTS至Ubuntu 22.04 LTS后，服务器每10分钟冻结，无法使用ssh和串行控制台。日志中无相关错误信息。通过浏览syslog文件发现，服务器在冻结时自动进入睡眠状态。问题可能是由于安装了gnome桌面环境导致的。解决方法是移除所有与gnome相关的软件包。
