Description (last modified by )
On my Lenovo ThinkCentre M93 one core is being consumed by the acpi_task constantly.
The syslog is also full of continuously-generated messages along the lines of:
KERN: usb hub 2: KERN: port 19 is not suspended KERN: usb hub 2: port 19 is not in an over current state KERN: usb hub 2: port 19 was reset KERN: usb hub 2: KERN: port 20 is not suspended KERN: usb hub 2: KERN: port 20 is not in an over current state KERN: usb hub 2: port 20 was reset KERN: usb hub 2: KERN: port 18 is not suspended KERN: usb hub 2: KERN: port 18 is not in an over current state KERN: usb hub 2: port 18 was reset

These look like two unrelated problems. The USB errors seem to come from the XHCI (USB3) driver, in my case I get those all the time but they don't result in excessive CPU use.
