我在 19.10 和现在的 20.04 中遇到了这个问题。我在 2020 年 2 月用它构建了这台计算机的 18.04 没有这个问题。我对 20.04 进行了全新安装。简而言之，在 FireFox 中滚动一段时间（几分钟到一小时）后，鼠标变为非活动状态（我可以移动它，但点击不注册），几秒钟后系统变得完全无响应，通常为空白或错误-彩色低分辨率屏幕，需要硬启动才能重置。
通常，这发生在从挂起恢复之后，但也发生在新启动之后（更罕见）。然而，这是一个间歇性问题，我不能确定前提条件是什么。在 FireFox 中滚动似乎或多或少是一个持续的触发器。我的怀疑是恢复或初始化时存在一些竞争条件，导致 amdgpu 驱动程序出现不正确的条件。我通过 syslog 中的错误搜索了这个问题，并遵循了我可以收集到的线索 - 从 AMD 站点重新安装 amdgpu 驱动程序，更新内核（现在为 5.8.1），但没有任何帮助。系统日志错误总是以：

当然，可以提供更多详细信息。任何建议都欣然接受。我发现最近使用 Linux 太容易崩溃了。

我在错误报告中看到了类似的错误，总是涉及 AMD 显卡，但主要是集成 APU，而不是我的离散设置。这个问题出现在我从 Ubuntu 18.04 迁移到 19.10 的过程中，其他人表示更新的内核修复了它，但更新到 5.8.1 并没有帮助我。鉴于问题的间歇性，其他人可能只认为它已经消失，而我见过的几个人注意到它又回来了。到目前为止，在我读过的几十个线程中都没有看到任何解决方案。我想我可以尝试放入一个较旧的视频卡，看看是否可以缩小范围。谢谢！

此时屏幕为空白，系统冻结。它看起来和往常一样。GPU重置被重试并超时并且失败所以在我看来，发生的事情是GPU在挂起后无法恢复/重置。我在重新启动时看到过它，但很少见，而且我通常可以工作/玩几个小时——只要我不允许它暂停。谢谢！
