From mboxrd@z Thu Jan 1 00:00:00 1970 From: Tom Tucker Subject: [ofa-general] [PATCH] amso1100: QP init bug in amso driver Date: Tue, 24 Jul 2007 14:31:52 -0500 Message-ID: <1185305512.20489.6.camel@trinity.ogc.int> Mime-Version: 1.0 Content-Type: text/plain Content-Transfer-Encoding: 7bit Cc: netdev@vger.kernel.org, OpenFabrics General To: Roland Dreier Return-path: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: general-bounces@lists.openfabrics.org Errors-To: general-bounces@lists.openfabrics.org List-Id: netdev.vger.kernel.org Roland: The guys at UNH found this and fixed it. I'm surprised no one has hit this before. I guess it only breaks when the refcount on the QP is non-zero. Initialize the wait_queue_head_t in the c2_qp structure.
