Date: Sat, 19 Apr 2014 03:15:54 +0200 From: Michael Leun <lkml20140418@...ton.leun.net> To: linux-kernel@...r.kernel.org Cc: ath9k-devel@....qualcomm.com, linux-wireless@...r.kernel.org, ath9k-devel@...ema.h4ckr.net Subject: 3.14 Regression, kernel panic when suspend, looks ath9k / wireless related 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.
