The following reply was made to PR kern/140036; it has been noted by GNATS. From: Bernhard Schmidt <bschmidt@techwires.net> To: bug-followup@freebsd.org, kaduk@mit.edu Cc: Subject: Re: kern/140036: [iwn] [lor] lock order reversal with iwn0_com_lock and iwn0 softc lock Date: Thu, 29 Oct 2009 08:19:44 +0100 Hi, Removing the IWN_LOCK(sc) leads to races when calling iwn_cmd(). It's better to drop the IEEE80211_LOCK(ic). I do have a patch in test which hopefully will hit the tree soon. -- Bernhard
