Played around with various combinations of the iwlwifi module parameters '5ghz_disable=1', '11n_disable=1' and 'swcrypto=1' using kernel 3.8.0-24 without any success. The -23 kernel continues to work fine (no special iwlwifi parameters).
The -24 kernel changelog [http://changelogs.ubuntu.com/changelogs/pool/main/l/linux/linux_3.8.0-24.35/changelog] does mention a few wifi-related fixes, perhaps one of them is the culprit.
