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?

Thank you for taking the time to report this bug and helping to make Ubuntu better.
Bug reporting is about finding & fixing problems thus preventing future users from hitting the same bug.
I suspect a Support site would be more appropriate, eg. https:/
If you upgraded to (k)Ubuntu 23.10 and rebooted & were able to login, then the ubuntu-
IO error would imply a problem that needs exploration; if you can get SysRq responses then its not a crash/freeze of the base system, maybe free of GUI/or display output only. You can explore systemd logs (journalctl) & look for clues (dmesg being an example of a command only showing details of current boot thus won't be helpful if you've rebooted). This though is support related.
I'll change package to 'linux' due to it working with older 6.2 kernel & reported issue only when using newer 6.5 kernel.
Please execute the following command only once, as it will automatically gather debugging information, in a terminal:
apport-collect 2042706
When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https:/
