and only upgrading from "nvidia-304 304.131-0ubuntu5" to "nvidia-304 304.132-0ubuntu1"
brings up this problem.

On the other hand, staying on "nvidia-304 304.131-0ubuntu5" and doing a complete "apt-get dist-upgrade" otherwise, results in a completely functioning system.

So looks like this problem is more connected with nvidia-304 versions than kernel versions.

My workaround is (thanks to BTRFS allowing me to boot into various snapshots and having the earlier driver version available):

$ cat /etc/apt/preferences.d/nvidia-304_mtrr-prob.pref
Package: nvidia-304
