由于某种原因，当我使用rtcwakewithdisk选项时出现错误：
$ sudo rtcwake -m disk -s 60
[sudo] password for rail:
rtcwake: assuming RTC uses UTC ...
rtcwake: wakeup from "disk" using /dev/rtc0 at Fri Jan 6 22:54:19 2023
rtcwake: write error
当我使用选项时一切正常mem。有人遇到过这样的问题吗？类似的问题已经被问过，rctwake：使用磁盘选项时出错。我确实要求更新，并被要求重新发布作为我自己的问题。
这是我的输出dmesg | grep -i ACPI

答案1
可能有许多与硬件相关的因素可能会影响对 的调用的行为rtcwake。从我上面的评论中您已经可以看出，拥有有关操作系统和硬件配置的诊断和数据至关重要。
也就是说，我对其rtcwake自身进行了跟踪：
> sudo strace -Tyfe trace=open,read,write rtcwake -m disk -s 60 2&>~/Output.txt
对我来说，这使我的机器进入“磁盘”睡眠状态，并在醒来并转储以下内容时Output.txt：
read(3</usr/lib/libc.so.6>, "\177ELF\2\1\1\3\0\0\0\0\0\0\0\0\3\0>\0\1\0\0\0P4\2\0\0\0\0\0"..., 832) = 832 <0.000025>
read(3</sys/power/state>, "freeze mem disk\n", 255) = 16 <0.000032>
ssuming RTC uses UTC ."..., 107rtcwake: assuming RTC uses UTC ...
rtcwake: wakeup from "disk" using /dev/rtc0 at Mon Jan 16 03:58:56 2023
) = 107 <0.000028>
write(4</sys/power/state>, "disk\n", 5) = -1 ENODEV (No such device) <2.365407>
正如我所评论的那样，rtcwake以"disk"set 作为参数，正在写入/sys/power/state.
相当于：
> echo disk > /sys/power/state
希望这可以帮助！
