Summary0008025: Kworker kernal process seems to cause high CPU usage
Description

Kworker kernel process causes high single core CPU usage. It seems to have something to do with the USB kernel modules. Running "sudo rmod xhci_pci" causes high CPU usage to stop, but I am unable to use any USB devices. Perf logs are attached to the case.

Plugging in a USB device seems to resolve the issue until the device is unplugged. Unplugging the USB device causes the CPU usage to spike back up to 100% on core 2.

Device: Lenovo Yoga 7I
CPU: 11th gen i5
Version: Kali Linux
Kernel: 5.19.0-kali2-amd64

Steps To Reproduce

No reproduction as of yet. The issue is persistent only on my laptop.

This is something that should be reported to the kernel bugzilla, as we do not touch the usb subsystem with any of our patches.
