I had this issue too on AWS.

In my case, it was the udev rule for vm-hotadd and the fix as mentioned previously basically came down to "touch /etc/udev/rules.d/40-vm-hotadd.rules" which effectively disables the /lib/udev/rules.d/40-vm-hotadd.rules file (after a reboot).

The udev rule basically seems to only be active for Xen or Hyper-V and while it seems the Hyper-V stuff was also present in previous versions, the Xen stuff seems to be introduced in 15.10 or newer.

So if you're seeing this issue on anything running on Xen, including AWS, try:

touch /etc/udev/rules.d/40-vm-hotadd.rules
reboot

This is probably a bug in Xen or a bug in the kernel.
