Date: Mon, 15 Aug 2011 15:40:53 GMT [thread overview]

pointer dereference)
Product: Networking
Version: 2.5
Kernel Version: 3.1-git
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Other
AssignedTo: acme-f8uhVLnGfZaxAyOMLChx1axOck334EZe@public.gmane.org
ReportedBy: bernd.schubert-97jfqw80gc6171pxa8y+qA@public.gmane.org
CC: linux-rdma-u79uwXL29TY76Z2rM5mHXA@public.gmane.org

Each time when I start IPoIB with any 3.1-rcX git version I tested so far I get
a kernel panic. This didn't happen in 3.0 yet.
