解决方案
我找到了这个文章。我已经将内核更新至最新版本 5.8，并且它可以正常运行。
答案1
您遇到了页面错误和 Nvidia 错误。
BIOS
您的 BIOS 当前版本为 0808。
英伟达
您拥有 Nvidia 版本 440。
有更新的版本可用，版本 450.57，可以下载这里。
直接下载这里。
交换
让我们替换一个可能有问题的 /swapfile，并将其扩大到 4G。
笔记：命令使用不当dd可能导致数据丢失。建议复制/粘贴。
sudo swapoff -a # turn off swap
sudo rm -i /swapfile # remove old /swapfile
sudo dd if=/dev/zero of=/swapfile bs=1M count=4096
sudo chmod 600 /swapfile # set proper file protections
sudo mkswap /swapfile # init /swapfile
sudo swapon /swapfile # turn on swap
free -h # confirm 32G RAM and 4G swap
reboot # reboot and verify operation
将此行添加到 /etc/fstab...
/swapfile none swap sw 0 0
记忆
去https://www.memtest86.com/并免费下载/运行它们memtest来测试你的记忆力。至少完成一次所有 4/4 测试以确认记忆力良好。这可能需要几个小时才能完成。
更新＃1：
有一个错误。请参阅https://bugzilla.kernel.org/show_bug.cgi?id=206653。已将内核更新至 5.8 并且现在可以运行。
