Actually, I'm getting something similar: usb 2-2: USB disconnect, address 23 PM: Removing info for No Bus:usbdev2.23_ep83 usb0: unregister 'cdc_ether' usb-0000:00:1d.0-2, CDC Ethernet Device PM: Removing info for No Bus:usb0 unregister_netdevice: waiting for usb0 to become free. Usage count = 1 unregister_netdevice: waiting for usb0 to become free. Usage count = 1 unregister_netdevice: waiting for usb0 to become free. Usage count = 1 unregister_netdevice: waiting for usb0 to become free. Usage count = 1 unregister_netdevice: waiting for usb0 to become free. Usage count = 1 unregister_netdevice: waiting for usb0 to become free. Usage count = 1 PM: Removing info for usb:2-2:1.0 PM: Removing info for No Bus:usbdev2.23_ep81 PM: Removing info for No Bus:usbdev2.23_ep02 The unregister_netdevice made it onto console, that means pretty severe log level. Happened while playing with openmoko connected with USB cable.
