每当我连接 USB 电话时，我就无法再暂停我的计算机。即使拆下我的手机也不起作用。

答案1
此类问题与硬件相关（ACPI 表）。当 Linux 系统启动时，您可以在输出中找到以下几行dmesg：
[ 0.x] ACPI : EC: interrupt unblocked
[ 0.x] ACPI : EC: event unblocked
我相信您的日志中不存在第二个（不确定这是这里唯一的问题）。也许尝试更新您机器的 USB 驱动程序或固件。
如果问题在实时操作系统（来自 USB）上仍然存在，则可能是与您的固件（SMI / ACPI 实现）有关的问题。
如果您无法通过更新解决此问题，则可能需要检查与“挂起”或 S3 恢复相关的 DSDT 或 SSDT 表（包含 ACPI 过程的 AML 代码）。
有关这些过程的更多详细信息，请查看 ACPI 文档：https://uefi.org/sites/default/files/resources/ACPI_6_2.pdf#G8.1371219
