Some blurbs from the web links above:

On language
His best-known work in phonology is The Sound Pattern of English, written with Morris Halle (and often known as simply SPE). Though extremely influential in its day, this work is considered outdated (though it has recently been reprinted), and Chomsky does not publish on phonology anymore.

On behaviour:
Chomsky's 1959 review has drawn fire from a number of critics, the most famous criticism being that of Kenneth MacCorquodale's 1970 paper On Chomsky’s Review of Skinner’s Verbal Behavior (Journal of the Experimental Analysis of Behavior, volume 13, pages 83-99). This and similar critiques have raised certain points not generally acknowledged outside of behavioral psychology, such as the claim that Chomsky did not possess an adequate understanding of either behavioral psychology in general, or the differences between Skinner's behaviorism and other varieties; consequently, it is argued that he made several serious errors.

To his credit:
Chomsky has also commented on critiques of "white male science", stating that they are much like the anti-Semitic and politically motivated attacks against "Jewish physics" used by the Nazis to denigrate research done by Jewish scientists during the Deutsche Physik movement:

In fact, the entire idea of "white male science" reminds me, I'm afraid, of "Jewish physics".

Chomsky has made connections between his linguistics research and more political topics. An example is a 1971 debate with French philosopher Michel Foucault on the question of human nature, where Chomsky used the idea of innate linguistic capacity to criticize the idea that all human values and knowledge are entirely conditioned by societal conditions. However, Chomsky makes such connections only rarely, and is generally critical of the idea that competent discussion of political topics requires expert knowledge in academic fields.

So he is no Derrida, at the very least.
