3.14 Regression, kernel panic when suspend, looks ath9k / wireless related

From: Michael Leun

Hi,

since 3.14 I get an kernel panic when trying to suspend or hibernate (and in several other situations). Looks ath9k or wireless related, does not happen when I for test remove /lib/modules/3.14.1/kernel/net/wireless/ath* (also from initrd).

Did not bisect yet, but could if needed.
