I got some external cooling for this laptop & the problem went away.
I've run some intensive GPGPU + CPU processing for some hours with no
problems showing up. I have the 8400M GT running fine under Ubuntu
16.04. Removing myself from the "affects me" list.

out the internal fan died; just happened to coincide with the update. I
have a solution for that on the way & plan to try again without the
overheating. Will come back to this after the repair.
