[Bug 2042706] [NEW] Kubuntu 23.10 freezes

[Kyrylo Bohdanenko]

Public bug reported:

I have upgraded from Kubuntu 23.04 to Kubuntu 23.10.

After working for 2-7 minutes, everything becomes extremely unresponsive
and freezes afterwards. The screen goes black (as if graphical shell has
crashed and I am in the terminal). However, the whole system remains
unresponsive. I cannot switch between terminals too (Ctrl+Alt+F<num>)

There was one symptom. When I was working in a Konsole window, and it
went unresponsive. Then I managed to launch another window, and every
single command returned "Input/output error" e.g.:

$ ls
bash: /usr/bin/ls: Input/output error 

I noticed I can work around the issue by switching from the 6.5.0 kernel
to the older 6.2.0 one which was left from Kubuntu 23.04.

The exact kernel package versions are:
* linux-image-6.5.0-10-generic
* linux-image-6.2.0-36-generic

How can I debug the issue?
