I have freezes on my system and i found a post with a solution

I have freezes on my system and i found a post with a solution which is to downgrade the kernel. pid=2293626#p2293626

Should i downgrade my kernel or is there a downside to doing so?

Also as a secondary question for the future. How can i diagnose this solo without needing to revert to this forum?

I know its journalctl im just looking for a summary of like 5 most common sitsuations. If your response is "read the man page" im going to do that after this post no need to post that

Re: I have freezes on my system and i found a post with a solution

The kernel is fairly isolated and generally safe to downgrade, especially if you don't rely on out of tree kernel modules like the nvidia driver (and in that case the header packages and the dkms will cover the vast majority of issues you might run into) you could also try (especially for having a backup of some sort) to just have multiple kernels e.g. the LTS kernel installed as well or so.

As for the journal commands, for the vast majority of cases using -b to filter the boot you're looking at is most useful e.g. -b for your current boot, if you were forced to reboot, -b-1 for the boot before your current boot and so forth. https://wiki.archlinux.org/title/System … ing_output contains some other useful commands to filter e.g. to a specific time range or so.

As for what exactly to look for, there's no generic answer to that and depends on case by case, in the thread you responded to, the reporting user managed to isolate it to amdgpu failures, whether that's the case for you specifically you will have to find out. And from there if you see something that looks off, the usual dance of googling whether someone has seen something similar, posting it here so experienced people can weigh in or going to the bug trackers of the relevant projects will likely go a long way.

Alright
1. Downgrade and have multiple for sitsuations like this
2. -b flag
3. i would figure its the kernel as this did not happen before kernel update. Im looking to fix this ofc so if this is not it then im just wrong but i remember when i update the kernel even though i dont remember half of the packages. The kernel stands out

Ty i remember im supposed to edit post title but i could not figure it out pre response. If its not changed can you respond with instructions. On how im supposed to achieve this

There are no specific buttons for this, you can just edit the thread title by editing your original post in the thread. It might be that you're exceeding the char limit (am fuzzy on the exact number) if you're not able to submit the post.
