can't enter S3 sleep after upgrading to 6.9.1

[eweitzman]

The os returns "No such file or directory" when I try to put unraid to sleep by this command:

 

echo 3 > /proc/acpi/sleep

 

The directory is there and appears to be writable. The file "wakeup" is there. I can cd to /proc/acpi. I get the same error trying to create any file in /proc/acpi. User is root: sudo shows no difference.

 

This is behaving as if the directory or partition is read-only.

 

root@unraid:/proc/acpi# pwd
/proc/acpi
root@unraid:/proc/acpi# whoami
root
root@unraid:/proc/acpi# echo 3 > sleep
bash: sleep: No such file or directory
root@unraid:/proc/acpi# touch x
touch: cannot touch 'x': No such file or directory
root@unraid:/proc/acpi# ls -ld ../acpi
drwxrwxrwx 3 root root 0 Apr  3 12:27 ../acpi/

 

I have the Dynamix S3 Sleep plugin installed. The sleep menu item in the GUI header does not cause the system to sleep.

 

Any suggestions?

 

Thanks,

- Eric

Linux kernel versions 3 and up use (Unraid 6.9 uses kernel 5.10)

echo -n mem >/sys/power/state

Thanks. I'll check it out tomorrow after a parity check completes.
