Public bug reported:
Summary
-------
I installed Ubuntu 16.04 LTS on a virgin box, specifically:
Hardware: BOXNUC5CPYH, Intel Celeron N3050 Processor, DDR3L SDRAM, Support
2.5in HDD/SSD, Gigabit Ethernet, WiFi, Bluetooth, USB 3.0, HDMI.
BIOS/EFI: PYBSWCEL.86A.0058.2016.1102.1842
4GB and 8GB RAM
500G SATA3 HD
VGA console with USB keyboard. No mouse.
Process
-------
Wipe HD
Boot with USB 16.04 LTS d2d939ca0e65816790375f6826e4032f
*ubuntu-16.04.1-server-amd64.iso (MD5) constructed with mkusb-nox on a known
functional Ubuntu Server box running 16.04 LTS.
Walk through setup steps using defaults and connected to internet through
firewall router.
Remove USB boot stick as instructed.
This was repeated at least 4 times with both 4GB and 8GB RAM sticks (new).
Current and expected result
---------------------------
System restarts as expected. Just prior to the console login screen, the
following message appears:
[ OK ] Started Dispatch Password Requests to Console Directory Watch
[ 40.123457] NMI watchdog: BUG: soft lockup - CPU#0 stuck for 22s!
[systemd-udevd:1129]
It remains like this indefinitely. Power-cycle required.
I expected the boot to complete and the console login to appear.
NOTE: If I go to Ubuntu 16.10 server using the same system and
procedure, Ubuntu 16.10 boots as expected and I can get to the console
login as expected.
