Message-ID: <4E4CFB06.8000203@fastmail.fm> Date: Thu, 18 Aug 2011 13:44:06 +0200 From: Bernd Schubert <bernd.schubert@...tmail.fm> To: Erez Shitrit <erezsh@....mellanox.co.il> CC: linux-rdma@...r.kernel.org, netdev@...r.kernel.org Subject: Re: [Bug 41212] New: [regression] [3.1-git] ipoib causes kernel panic (NULL pointer dereference) Hello Erez, maybe it is another bug?
