Interesting Question and Answer about what does it mean that the walls reach the S'cach: http://www.mail-archive.com/daf-discuss%40shemayisrael.co.il/msg01120.html

It states in Succah 2a, the pasuk from Isiah (4:6) that is basis of the opinion of R' Zeira regarding the reason why the Sukkah cannot be more than 20 amos tall. Later, this is disregarded by the other two opinions on the next amud (though R' Zeira has a backing based on the wording) as incorrect due to the pasuk describing the times of Moshiach. Rabbeinu Chananel has a note on this in the bottom corner of 2a (v'R Zeira sukkah limut hamashiach he. Klomar... asbout 10 lines from the bottom), for English see Artscroll Schottenstein Edition 2b1, note 4.
The following drasha explains this idea further amongst related ones:

You need the Ran to follow along. Analyzing the Mishna's Sun v. Shade matter (2a), Rashi's comment on them by the Ran, mentions other sources too.
