Date: Mon, 6 Dec 2010 11:06:31 +0000 (UTC) From: Frederik Himpe <fhimpe@...enet.be> To: netdev@...r.kernel.org Subject: 2.6.32 bnx2: unable to handle kernel NULL pointer dereference at (null) on OOM With kernel 2.6.32.15 I can reproducibly kill networking on a system using the bnx2 driver by starting up memory hogs triggering the OOM killer. I could not find any indication in the 2.6.32 stable changelogs that this is fixed in a later 2.6.32 update. Here is the log including the OOM killer traces and the bnx2 null pointer deference captured with netconsole: Dec 5 19:26:19 node001.cvos.cluster [4445292.253420] IN invoked oom-killer: gfp_mask=0x280da, order=0, oom_adj=0 Dec 5 19:26:19 node001.cvos.cluster [4445292.253498] Pid: 30009, comm: IN Not tainted 2.6.32.15 #1 Dec 5 19:26:19 node001.cvos.cluster [4445292.253559] Call Trace: Dec 5 19:26:19 node001.cvos.cluster [4445292.253624] [<ffffffff8106bd0c>] ?
