Hi,

I am facing a similar from as in
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1255777, i.e.,
after resuming from suspend mode its one of the core/thread is being
used heavily by the kworker process, resulting in freezing in every
second. Even when audio or video is played it's stopping.

Please refer to the video and screenshot of the system monitor and top in the following link.

Is there a solution for this.

System details:
Hardware: ThinkPad E14 Gen 6
Processor: Intel Core Ultra 7 155H
OS: Ubuntu 24.02.1 LTS
Kernel: Linux 6.8.0-47-generic
Firmware (BIOS): R2JET37W(1.14)

Thanks and regards,
Saumyen
