Ubuntu 20.04 无法在我的三星笔记本电脑上启动“rcu_sched 检测到 CPU/任务停顿”

Question

你好，我将我的笔记本电脑（规格在底部）从 ubuntu 19 更新到了 ubuntu 20.04，然后我遇到了 amd gpu 的问题，我通过替换解决了这个quiet splash问题radeon.modeset=0 （我的计算机启动时出现黑屏，我该怎么做才能修复它？）

完成这些之后，在启动时我看到了错误消息rcu_sched detected stalls on CPUs/tasks ，并且它卡在那里大约 20 分钟，没有继续

我在 askubuntu 上看到了其他问题的相同标题，但它们要么是 ubuntu 的旧版本，要么是不同的硬件/GPU，要么没有建议的解决方案

问题

当我尝试从我的 U 盘启动 ubuntu 20.04 时也遇到了同样的问题
