Of course I can't be sure if the kernel change itself has caused the
problem or if it is grub related. Too many things were changed in the
one big update that brought this on.
I found one other person having a similar problem over on the Debian
user forums: http://forums.debian.net/viewtopic.php?f=10&t=130252
Their solution was to update to an experimental 4.8 kernel.
I'm able to boot the machine to kernel 4.6.0 and keep moving.
So I guess I'll just wait and see.
Thanks for the support.
