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) linux-image-6.8.0-35-generic/noble-updates,noble-security,now 6.8.0-35.35+1 amd64 [installed,automatic] linux-image-generic-hwe-24.04/noble-updates,noble-security,now 6.8.0-35.35 amd64 [installed,automatic] linux-image-unsigned-6.4.0-060400-generic/now 6.4.0-060400.202306271339 amd64 [installed,local] linux-image-unsigned-6.9.3-060903-generic/now 6.9.3-060903.202405300957 amd64 [installed,local] -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2061840 Title: Ubuntu 24.04 freezes after plug in power cable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2061840/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
