Kernel oops while "multitasking"

[tabimeter]

Hi,

I’ve encountered a kernel oops. I’ve had multiple applications open like: libreoffice (fresh), makmkv (as a flatpak) zotero (as a flatpak), Firefox, gnome terminal (4 Tabs, 2 with ssh connections).

I have a second screen connected to my Laptop via HDMI and a mouse/Keyboard via a USB Hub.

Before the oops happened I’ve closed makemkv and used the gnome terminal to log in to two machines with ssh while watching a YouTube video. When i logged on the second ssh session the Videooutput (of the screen) froze but my audio from YouTube played fine. I couldn’t stop the YouTube playback with the keyboard but i was able to pause it with kdeconnect/gsconnect (lol). In the end nothing worked anymore and i shut my Laptop down with the hold of the Power button.

Logadress is: http://ix.io/4DhO (I’ve edited it a little bit bc of privacy :))

Thanks in advance (and thanks for the Distro so far, love it :))

Welcome to the forum.

i shut my Laptop down with the hold of the Power button.

Don’t do that.

Do this instead:

[Tip] Enable Magic SysRq Key (REISUB)

The Linux kernel authors have provided a very nice feature of issuing low-level commands to the kernel directly, regardless of the state the system is in. This is called the “Magic SysRq Key”, because these commands are issued by pressing the SysRq key on the keyboard (if you can’t find it, typically, it shares the same physical key as the Print Screen key, but on some laptops it can be elsewhere). A common use is to reboot when the computer freezes and becomes unresponsive due to some software…

If the issue doesn’t repeat itself to the point of being disruptive to the workflow, I don’t think there is any point in trying to troubleshoot it.
