[Zakaria Farhati]

I have Ubuntu 24.04 installed on my laptop, when I plug in my power cable to my laptop, the whole Ubuntu freezes and nothing is responds, so I have to force shutdown my laptop and restart it. I want to make notice that all other version Ubuntu 23.10, 22.04... with all different flavors work perfect without any issue

Hello,

Could you please try again with the latest 24.04 image? It has a more recent kernel version (6.8.0-31.31) and before we start investigating we need to know if it is still reproducible with the latest kernel available.

[Zakaria Farhati (farhatizakaria)]

Hello Kleber, I have installed the lastest 24.04 image with Linux ubuntu 6.8.0-31-generic. The issue still exist !

[Mariusz Ostrowski (mariuszostrowski)]

Hello everyone,
I have exactly the same problem. The computer works perfectly on the power supply, but on the battery, especially when the power supply is connected, it freezes completely. It works flawlessly on Windows. Previously - 23.10 - it also worked properly

[Juerg Haefliger (juergh)]

Does this also happen with the latest kernel 6.8.0-35? Is there anything in the log from the freeze? After a freeze, reboot and pull the log from the previous boot (journalctl -b -1).

[Zakaria Farhati (farhatizakaria)]

Yes it still happens with the latest kernel 6.8.0-35. And, here's the log extracted after reboot: https://paste.ubuntu.com/p/GvXgHk29CX/

After further testing, I wanted to share additional information that might assist in diagnosing the issue. I have tested kernel version 6.4.0-060400-generic as an alternative and found that the issue does not occur when I plug in or plug out the power cable (everything works fine). This kernel version (6.4.0) appears to handle power state transitions correctly compared to kernel 6.8 (also I tested 6.9.3-060903 and I found that it has the same issue/bug as 6.8).

$ apt list --installed | grep linux-image (Here're the kernels that I have at this moment, only 6.4.0 runs without any issue)
