Are references with indication of page number uncommon in computer science? I am writing a computer science paper in which I cite several lengthy sources (text books and standard specifications). Whenever I cite such a source, I add the page numbers of the subsection to which I refer, e.g.: 


  Bla bla is considered very important [52, pp. 210-214].


One of the reviewers of the paper remarks the following:


  Do not use references with indication of page numbers (e.g., [52, pp. 210-214]), this is very uncommon.


Is this really true (in computer science)?

Am I wrong to include the page numbers in the reference?

The reference in question is a 400+ page book that broadly covers a whole subject area and I thought knowing which pages I actually refer to might help the reader. There are several other (and longer) sources, such as technical standards, which I cite in the same fashion.
Specifying which part of a long book or article you are referring to in your citation is a sound practice, but in general section, theorem or equation numbers are more common than page numbers for this task: [52, Section 3.5] or [52, Equation 3.23] rather than [52, Page 132-134].

Personally I use page numbers only as a last resource where nothing else is available: that is, when the section or equation I want to refer to does not have a number of its own.

I do not have a compelling reason for this, if not that section numbers are more robust to minor pagination changes, but this is the behaviour that I have seen more commonly.
