在 AMD Ryzen 2700X + RTX 2080 + Ubuntu 18.04 堆栈上，系统经常冻结

我使用上述设置，使用 python MXNet 进行深度学习计算。

当我使用 unity/gnome 时，崩溃之前journactl会报告类似这样的情况（总是 gnome 相关的进程先崩溃）：

-- Reboot --当我注意到系统冻结并按下重启按钮时。

现在，我已切换到 xfce4 桌面管理器。它运行了很长时间，我对其进行了整夜测试。当我回到 PC 时，屏幕上显示随机的矩形彩色斑块。最后一行显示journalctl：

snapd[911]: stateengine.go:102: 状态确保错误：无法刷新“核心”的 snap-declaration：获取 https://api.snapcraft.io/api/v1/snaps/assertions/snap-declaration/16/*******?max-format=3：拨号 tcp：查找 api.snapcraft.io：没有这样的主机

我不确定问题是否真的是 ubuntu 桌面管理器无法正确与 NVidia 通信，或者是 NVidia 驱动程序问题，或者是 Ryzen 问题......

也许有人有一些线索？

重要更新：在所有可以追踪的情况下，崩溃都是在 np.loadtxt(...) 操作非常大的文件（实际上是训练数据集）期间发生的。
