偶爾 Gnome 桌面崩潰，[2175]：cr_parser_new_from_buf：斷言「a_buf && a_len」失敗，20.04.3 LTS

使用 Nvidia GeForce RTX 3080 運行 Digital Storm 伺服器，桌面偶爾會崩潰或凍結。我們已經運行了 20.04.3 LTS、GNOME Shell 3.36.9 和 5.11.0-34-generic 核心的所有 apt 更新和升級。

可能無關我還看到：

這聽起來類似，有相同的錯誤，但現在是 21.04。我們最近禁用了冬眠功能，或者至少我們認為我們做到了。

sudo systemctl status sleep.target suspend.target hibernate.target hybrid-sleep.target

事實證明，這些消息有點轉移注意力。儘管 GDM 可能仍然存在問題，但真正的問題是至少有一個記憶體模組損壞，這就是導致凍結的原因。更煩人的是我們無法運行 Memtest86，因為系統需要工作記憶體晶片才能引導到 USB/DVD！
