Subject: [BUG bisected] WARNING: CPU: 0 PID: 1550 at net/wireless/chan.c:373 cfg80211_chandef_usable+0x30/0x15f()
Date: Mon, 21 Oct 2013 14:09:40 +0200 [thread overview]
Message-ID: <gifvruyge3.fsf@karga.hank.lab> (raw)
Hello Simon, all,
Recently, I noticed many traces (find a sample attached) in situations
when wpa_supplicant is running but no appropriate access-point available.
I started a bisect and ended at commit 3aede78aad2a7e
(mac80211: change IBSS channel state to chandef).
Please let me know if you need more information to inspect this problem.
Best regards,
Dirk
