I use pdf tools as a viewing program. Just after I updated Linux and
Emacs last month a problem appeared. When I compile a document
consisting of, e.g., Ch01 and Ch02, while opening Ch01, the pdf visits a
page that is different from the one I am currently on LaTeX file. This
problem does not appear if the document consists of just one main tex
file.

Thanks a lot for the great recipe which made it rather easy to spot the
bug.  AUCTeX always called pdf-tool's sync function with the master
file, not the current file.  That should be fixed now and I took the
chance to release a new GNU AUCTeX version (11.89.2) via ELPA.  It
should be listed in `M-x list-packages' within the next 24 hours.

I checked the code and its revisions, and that wrong behavior has been
there for quite a long time.  I think, I've introduced that bug on
February 2015.  So in case you've used an older version and recently
upgraded to a newer AUCTeX version, that might have been the problem (or
actually a good thing since you've spotted the bug).

BTW, in case you don't already know, if you use PDF Tools as viewer,
it's usually a good idea to also add

  (add-hook 'TeX-after-compilation-finished-functions
             #'TeX-revert-document-buffer)

to your ~/.emacs.  That will revert the pdf-view buffer as soon as the
LaTeX compilation finishes so you don't have to do that manually.

Bye,
Tassilo
