This is very unlikely a problem with base-files, as the only change for
the point release is to raise /etc/debian_version from 9.2 to 9.3 (so
that the exact point release is shown in bug reports like this one).

So I am reassigning this to chromium and the kernel.

However, please be ready to provide the chromium and kernel maintainers
with additional info as they ask, because this could be a bug in other
packages too.

[ I would bet this has something to do with the kernel. To be sure
  try installing the kernel in Debian 9.2 (from snapshot.debian.org) and
  see if the problem disappears when using the old kernel ].
