| Summary | 0008025: 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. |
