Removed virtualbox-dkms, video driver changed from NVIDIA to Nouveau, installed kernel v 4.8.0-040800, three times performed cold boot (dmesg' outputs attached): boot times was much shorter, BUT dmesg still prints that "error -110". Removed kernel 4.8 (not installed virtualbox-dkms, video driver still Nouveau): returned to previous state with long boot and errors in dmesg output.

I experience this behavior about half of year or so I think (with 14 LTS I had no pause at bootups). I analyzed dmesg output (full printout is attached) and found that cause for this pause is integrated bluetooth (notice pause ends at 23 second): $ dmesg|grep "usb 1-1.1" [ 1.973231] usb 1-1.1: new full-speed USB device number 3 using ehci-pci [ 2.067324] usb 1-1.1: New USB device found, idVendor=13d3, idProduct=3362 [ 2.067327] usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 2.067329] usb 1-1.1: Product: Bluetooth USB Host Controller [ 2.067330] usb 1-1.1: Manufacturer: Atheros Communications [ 2.067331] usb 1-1.1: SerialNumber: Alaska Day 2006 [ 3.039098] usb 1-1.1: USB disconnect, device number 3 [ 3.241427] usb 1-1.1: new full-speed USB device number 5 using ehci-pci [ 8.313589] usb 1-1.1: device descriptor read/64, error -110 [ 23.898487] usb 1-1.1: device not accepting address 5, error -32 [ 23.970500] usb 1-1.1: new full-speed USB device number 6 using ehci-pci [ 24.064658] usb 1-1.1: New USB device found, idVendor=13d3, idProduct=3362 [ 24.064667] usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 24.064671] usb 1-1.1: Product: Bluetooth USB Host Controller [ 24.064674] usb 1-1.1: Manufacturer: Atheros Communications [ 24.064677] usb 1-1.1: SerialNumber: Alaska Day 2006 In fully booted system bluetooth is working without problems. Later restarts don't produce mentioned pause and dmesg doesn't show mentioned errors.
