在最近的 Ubuntu 内核更新之后，不同的 Thinkpad 设备都无法进入挂起状态。几乎每次它们在合上盖子后进入挂起状态时，都会被硬锁住，只有长按电源按钮（硬关机）才能恢复。
一个运行 E490 的案例5.0.0-25-generic：我相信盖子关闭是在/var/log/kern.log12:47 开始时，并且看起来发生了多次挂起尝试。13:39 是硬关机后的启动。：

以下是后来研究的一些结果，来自@nuts 的想法：
rmmod btusb使一切正常运行，挂起和唤醒工作正常（至少持续几秒钟，我没有检查电量消耗）。modprobe btusb返回具有新的行为：现在系统不会在挂起时停顿，而是会在挂起后立即自发唤醒。
关于如何进一步研究这个问题您有什么想法吗？
