我在使用 19.10 时遇到过这个问题，现在使用 20.04 时也遇到过这个问题。2020 年 2 月，我使用 18.04 组装这台电脑时没有遇到这个问题。我为 20.04 进行了全新安装。简而言之，在 FireFox 中滚动一段时间（几分钟到一个小时）后，鼠标变为非活动状态（我可以移动它，但点击没有注册），几秒钟后系统完全没有响应，通常出现空白或假色低分辨率屏幕，需要硬启动才能重置。
通常，这种情况发生在从挂起恢复后，但也发生在全新启动后（较少见）。然而，这是一个间歇性问题，我不能确定先决条件是什么。在 FireFox 中滚动似乎或多或少是一个持续的触发因素。我怀疑恢复或初始化时存在一些竞争条件，导致 amdgpu 驱动程序中的不正确条件。我通过 syslog 中的错误搜索了这个问题，并按照我能找到的线索进行了尝试 - 从 AMD 网站重新安装 amdgpu 驱动程序，更新内核（现在为 5.8.1），但都无济于事。Syslog 错误总是以以下内容开头：
8月18日 21:05:26 mvlLinux-pc 内核：[28611.718399] [drm:amdgpu_dm_atomic_commit_tail [amdgpu]]错误等待隔离超时！

硬件概要：

处理器：AMD Ryzen 5 2600X 六核处理器
显卡：Asus Strix Radeon RX570
内存：CRUCIAL 16 GiB
当然，还有更多详细信息。任何建议都非常感谢。我发现最近使用 Linux 太容易崩溃了。

我在错误报告中看到过类似的错误，总是涉及 AMD 显卡，但主要是集成 APU，而不是我的独立设置。这个问题出现在我从 Ubuntu 18.04 升级到 19.10 时，其他人表示较新的内核修复了这个问题，但更新到 5.8.1 对我没有帮助。鉴于该问题的间歇性，其他人可能只是认为它已经消失了，而我看到的几个人注意到它又回来了。到目前为止，我读过的几十个帖子中都没有看到解决方案。我想我可以试着装上一张旧显卡，看看是否能缩小范围。谢谢！

此时屏幕空白，系统冻结。看起来与平常差不多。重试 GPU 重置，超时并失败，所以在我看来，发生的事情是 GPU 在挂起后无法恢复/重置。我在全新重启时见过这种情况，但很少见，而且我通常可以工作/玩耍几个小时 - 只要我不允许它挂起。谢谢！

BIOS
华硕 PRIME X470-PRO
您的 BIOS 版本为 5406。

注意：确认我拥有您主板型号的正确网页。
注意：更新 BIOS 之前请做好备份。
记忆
Ryzen 处理器因内存兼容性问题而臭名昭著。
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：
交换
让我们将您的 /swapfile 从 2G 增加到 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 4G RAM and 4G swap
确认 /etc/fstab 中的此行...并确认没有其他“交换”行...
/swapfile none swap sw 0 0
reboot # reboot and verify operation
更新 #2：
我犹豫是否提供这个，因为我怀疑您的 AMD 显卡可能有缺陷......但您可以尝试一下......
AER（高级错误报告）
sudo -H gedit /etc/default/grub# 编辑此文件
寻找：
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
更改为：
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=noaer"
sudo update-grub# 更新 GRUB
reboot# 重启计算机
更新 #3：
断开了一堆 USB 设备，怀疑/恢复现在正在运行。怀疑是几个 USB 集线器。
答案2
heynnema 指出的答案是 - 问题可能是由有缺陷的 USB 设备引起的。目前还不确定哪个设备是真正的问题，但廉价的 USB 3.0 集线器似乎是问题所在。移除后系统稳定了。
答案3
我遇到了类似的问题，但在 radeon 上使用 Glamor（现在是基于卡 3D 加速的默认 2D 加速...我想），如果是这样，'选项“AccelMethod”“none”' 可能会有所帮助...起初我建议使用 EXA，但 man amdgpu 只说 none（或 glamor，我认为这会导致问题恢复）。请参阅https://bugs.launchpad.net/bugs/1944991
答案4
更新：
这可以解决我的鼠标间歇性死机的问题，它会重新启动鼠标，也可能会重新启动其他停转的设备。
sudo fwupdtool 获取设备
较旧：
使用 Ubuntu 20.04 gnome 的 ACER Aspire E 15 笔记本电脑发现相同/类似的鼠标冻结问题
到目前为止，我唯一的解决方案是使用 F 键（对于自身为 F3）打开终端。
然后命令完全关闭，然后重新启动。
关机后自行等待一小段时间然后重新启动
。
