|0008025||Kali Linux||[All Projects] General Bug||public||2022-10-27 04:05||2023-05-31 14:56|
|Target Version||Fixed in Version|
|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
|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.|
