Confirm that this bug happen to me too. I'm using Ubuntu 14.04.3 LTS and install new Kernel with command

sudo apt-get install -y linux-generic-lts-wily linux-tools-virtual-lts-wily linux-cloud-tools-virtual-lts-wily hv-kvp-daemon-init

Then reboot to get new Kernel 4.2.0-18-generic then systemd-udevd got high cpu usage instantly. If I run the command "udevadm monitor" it will show a lot of these repeat all the time.

UDEV [20358.123891] add /devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A03:00/device:07/VMBUS:01/vmbus_6722212 (vmbus)
KERNEL[20358.123989] remove /devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A03:00/device:07/VMBUS:01/vmbus_6722212 (vmbus)
UDEV [20358.124105] remove /devices/virtual/misc/vmbus!hv_vss (misc)
KERNEL[20358.124336] add /devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A03:00/device:07/VMBUS:01/vmbus_6722213 (vmbus)

KERNEL[20358.124403] add /devices/virtual/misc/vmbus!hv_vss (misc)
UDEV [20358.124753] add /devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A03:00/device:07/VMBUS:01/vmbus_6722213 (vmbus)
UDEV [20358.124853] add /devices/virtual/misc/vmbus!hv_vss (misc)

So I remove all wily kernel and back to vivid kernel then everything back to normal
