Followup-For: Bug #884116

I also encountered this problem after the latest apt update && apt upgrade. The system didn't crash, though -- just the annoying right-to-left flicker occasionally.

After asking around in #debian on freenode, I installed (with dpkg -i)
http://snapshot.debian.org/archive/debian/20170929T215212Z/pool/main/l/linux/linux-image-4.9.0-4-amd64_4.9.51-1_amd64.deb
and rebooted. The system works fine now.

Here is some information that I think is relevant (I'd be happy to supply more if requested):
