This laptop has a shared bluetooth and WiFi mini card, which has never worked properly (see attached hardware details). Although MWindows has no problem, in Linux I have to disable WiFi when I need to use bluetooth! O_o Anyway, I now discovered that bluetooth won't work and /lib/systemd/systemd- udevd --daemon is pegged at 100% of CPU time. Switching off the mini-card using a keyboard button does not stop udevd from running hot. It just drops from 100% to 45% until I kill the process manually. udevadm monitor shows: KERNEL[281.040708] bind /devices/pci0000:00/0000:00:1d.0/ usb2/2-1/2-1.6/2-1.6.2/2-1.6.2:1.0 (usb) KERNEL[281.040855] unbind /devices/pci0000:00/0000:00:1d.0/ usb2/2-1/2-1.6/2-1.6.2/2-1.6.2:1.0 (usb) UDEV [281.041192] unbind /devices/pci0000:00/0000:00:1d.0/ usb2/2-1/2-1.6/2-1.6.2/2-1.6.2:1.0 (usb) KERNEL[281.044485] bind /devices/pci0000:00/0000:00:1d.0/ usb2/2-1/2-1.6/2-1.6.2/2-1.6.2:1.0 (usb) KERNEL[281.044596] unbind /devices/pci0000:00/0000:00:1d.0/ usb2/2-1/2-1.6/2-1.6.2/2-1.6.2:1.0 (usb) UDEV [281.044969] bind /devices/pci0000:00/0000:00:1d.0/ usb2/2-1/2-1.6/2-1.6.2/2-1.6.2:1.0 (usb) KERNEL[281.048056] bind /devices/pci0000:00/0000:00:1d.0/ usb2/2-1/2-1.6/2-1.6.2/2-1.6.2:1.0 (usb) KERNEL[281.048257] unbind /devices/pci0000:00/0000:00:1d.0/ usb2/2-1/2-1.6/2-1.6.2/2-1.6.2:1.0 (usb) UDEV [281.048534] unbind /devices/pci0000:00/0000:00:1d.0/ usb2/2-1/2-1.6/2-1.6.2/2-1.6.2:1.0 (usb) KERNEL[281.051754] bind /devices/pci0000:00/0000:00:1d.0/ usb2/2-1/2-1.6/2-1.6.2/2-1.6.2:1.0 (usb) KERNEL[281.051995] unbind /devices/pci0000:00/0000:00:1d.0/ usb2/2-1/2-1.6/2-1.6.2/2-1.6.2:1.0 (usb) non stop.
