Comment 29 for bug 1723174

Installed latest test kenel:

sudo dpkg -i
linux-headers-4.10.0-36_4.10.0-36.40-lp1723174Commit582945ec835e_all.deb
linux-headers-4.10.0-36-generic_4.10.0-36.40-lp1723174Commit582945ec835e_amd64.deb
linux-image-4.10.0-36-generic_4.10.0-36.40-lp1723174Commit582945ec835e_amd64.deb
linux-image-extra-4.10.0-36-generic_4.10.0-36.40-lp1723174Commit582945ec835e_amd64.deb

then executed also:

sudo apt install --reinstall i915-4.11.6-4.10.0-dkms

(and finally executed also the intel Graphics Update).

Now 4.10.0-36 works fine; and also the 4.10.0-37 now works fine!!! [SOLVED]

So the problem seem to be just the automatic rebuild of the i915 module
during the upgrade (not a kernel issue but just the package setup automatic
procedure).
