Sluggishnes of system and weird journal errors

My system has become a bit sluggish again (after solving the last issue: link

I tried changing the kernel to (Linux LTS this time) but it didn't work.

I have also investigated a bit the journal errors. I managed to fix some, but the one that seems the most ominous still elludes me, and I don't know how to approach it (I tried googling some of the error lines t hat seemed meaningful to me, but didn't find anything that seemed to help).

Do you have any ideas what might be the reason for the panic reported in the journal ? (It happens everytime just after the boot).

Btw. for reference I use multimonitor setup with the notebook (which causes some problems from time to time, especially when putting notebook to sleep, but it should affect the clean start I guess).

ACPI errors are generally not a great concern.

Try this method for your poor system responsiveness:

Okay, but what about the errors below:

Mar 12 15:23:03 Hades kernel: ------------[ cut here ]------------

This seems to be some panic event (major error) or did I understand wrongly?

Anyway, thanks for your suggestions @tbg . I am currently testing your proposed solution.
I wasn't however able to delete all the snapshots. One of them was "not empty" and refused deletion.

I guess that's related to the topic of Docker and BTRFS (described [here])([btrfs] Docker and Subvolumes)

I don't use the docker massively at this moment, so the disk exhaustion isn't extensive, but probably I will need to try the approach described by the author of that post (reinstall the system and setup other filesystem engine for docker).

Still, I hope the deletion of the other snapshots (9 of them) and reballancing will bring some dragonly performance upgrades :dragon:

A new setup of the system is not necessary.

First of all, backup your data.
Stop docker.

You can delete all docker subvolumes:

After that I had some errors with docker, but simply uninstall docker, delete /var/lib/docker/ and install docker.
And then before starting docker for the first time stick to the solution.


Adding to that, after that a full btrfs balance might be good.

Haven't visited the forum for few days.

Thanks for the tip @BrutalBirdie, surely will use that :dragon:
