Question

运行配备 Nvidia GeForce RTX 3080 的 Digital Storm 服务器，桌面偶尔会崩溃或冻结。我们已针对 20.04.3 LTS、GNOME Shell 3.36.9 和 5.11.0-34-generic 内核运行所有 apt 更新和升级。

这听起来类似，错误相同，但版本是 21.04。我们最近禁用了休眠功能，或者至少我们认为我们禁用了。

事实证明，这些消息有点儿像是一种误导。虽然 GDM 可能仍然存在问题，但真正的问题是至少有一个内存模块坏了，这就是导致冻结的原因。更令人恼火的是，我们无法让 Memtest86 运行，因为该系统甚至需要一块正常工作的内存芯片才能启动 USB/DVD！
