first created backup ami , unheld these packages:

sudo apt-mark unhold linux-aws sudo apt-mark unhold linux-headers-aws sudo apt-mark unhold linux-image-aws sudo apt-mark unhold lxd sudo apt-mark unhold lxd-client

then updated:

sudo apt-get install linux-headers-aws linux-image-aws

this ran successfully:

setting linux-headers-aws (4.4.0.1026.29) ... setting linux-aws (4.4.0.1026.29) ...

several attempts reboot @ point rendered ami unconnectable error message in system log documented in question. re-downloaded ixgbevf according aws documentation , re-installed, commenting out version check line allow compilation (#if uts_ubuntu_release_abi > 255). required first uninstall existing ixgbevf-3.1.2 module:

sudo dkms remove ixgbevf/3.1.2 --all sudo dkms add -m ixgbevf -v 3.1.2 sudo dkms build -m ixgbevf -v 3.1.2 sudo dkms install -m ixgbevf -v 3.1.2 --all sudo update-initramfs -c -k sudo reboot

and able connect.
