[systemd] Version 245.6-1 breaks suspended + resume

[Sedat Dilek]

Hi Michael and Debian/systemd team,

hope you are well Michael.

Today, I switched over from systemd version 245.5-3 to 245.6-1 on
Debian/testing AMD64.

On the upgrade, I read there is a new version of journald.conf.
I have not checked what changed.

Here I have a 00-journal-size.conf file:

# cat /etc/systemd/journald.conf.d/00-journal-size.conf
[Journal]
SystemMaxUse=100M

I increased the value for SystemMaxUse from 50M to 100M (see below status).
Too small?
Unsure, if this is related or not.

And did a 2nd suspend and resume.
>From my memory:
Ext4-FS block issues
systemd-journald: /var/log/journal/... is read-only

The system is in an awful and unusable situation.
Typing any command in konsole shows command not known/found.
I have not found a way to debug this.

Known issue?
What informations do you need?
Can you give help on debugging?

BTW, I use a selfmade Linux v5.7.1 kernel if this matters.

I have not tried to downgrade to the previous version of systemd as I
have never done a suspend+resume for ages (here: KDE/Plasma).

Thanks.

Regards,
