Systemd | Hibernation fails after upgrading from 253.7 to 254 when failing to parse the resume_offset setting

kagetora13 · August 2, 2023, 2:09pm

After upgrading from systemd 253.7 to 254 I noticed hibernation stopped working and seeing the following eror in the system journals:

Aug 01 17:23:42 mani systemd-hibernate-resume-generator[100]: Failed to parse resume_offset=36151296..: Invalid argument
Aug 01 17:23:42 mani systemd-hibernate-resume-generator[100]: Failed to parse kernel command line, ignoring: Invalid argument

I confirmed hibernation was failing from terminal:

❯ systemctl hibernate
Call to Hibernate failed: Not enough swap space for hibernation

Note that my swap\hibernation file is 7.5 GB where my physical memory is 16 GB.

In order to get Hibernation to work again I downgraded to systemd build 253.7 (which was previously installed.

### systemd version the issue has been seen with 254 ### Used distribution En…deavourOS \ Arch ### Linux kernel version used 6.4.7-zen1-2-zen ### CPU architectures issue was seen on x86_64 ### Component other ### Expected behaviour you didn't see The system should go into hibernation when I execute "systemctl hibernate" from terminal. ### Unexpected behaviour you saw On boot I saw the following errors in the journal after upgrading from systemd 253.7 to 254: ``` Aug 01 17:23:42 mani systemd-hibernate-resume-generator[100]: Failed to parse resume_offset=36151296..: Invalid argument Aug 01 17:23:42 mani systemd-hibernate-resume-generator[100]: Failed to parse kernel command line, ignoring: Invalid argument ``` I then decided to test the Hibernation by starting it from terminal which failed: ``` ❯ systemctl hibernate Call to Hibernate failed: Not enough swap space for hibernation ``` Note that my swap\hibernation file is 7.5 GB where my physical memory is 16 GB. I did confirm the swap file was still active. In order to get Hibernation to work again I downgraded to systemd build 253.7 (which was previously installed. ### Steps to reproduce the problem 1. Upgrade from systemd 253.7 to 254 in the Arch Repository. 2. Reboot the system. 3. Check the journals and see the error reported: ``` Aug 01 17:23:42 mani systemd-hibernate-resume-generator[100]: Failed to parse resume_offset=36151296..: Invalid argument Aug 01 17:23:42 mani systemd-hibernate-resume-generator[100]: Failed to parse kernel command ``` 4. Try to hibernate from terminal and get the below error: ``` ❯ systemctl hibernate Call to Hibernate failed: Not enough swap space for hibernation ``` Workaround: Use downgrade to roll back from systemd 254 to 253.7. ### Additional program output to the terminal or log subsystem illustrating the issue _No response_

Looks like the resume_offset= is now being parsed by systemd-hibernate-resume-generator. So the “…” in mine is now considered invalid.

So not a bug but a feature.
