             Bug ID: 76781
            Summary: unable to handle NULL in xfrm_input+0x173, fatal
                     exception in interrupt
            Product: Networking
            Version: 2.5
     Kernel Version: 3.15.0-rc6
           Hardware: x86-64
                 OS: Linux
               Tree: Mainline
             Status: NEW
           Severity: normal
           Priority: P1
          Component: Other
           Assignee: shemminger@linux-foundation.org
           Reporter: cate@cateee.net
         Regression: No

It seems it happens "often": twice in last few hours I used the new kernels.
(the first oops was with 3.15.0-rc5-00270-gfba69f0)

I had also usual debian unstable updates, and I just finished to instal aiccu
(a sixxs program for dynamic ip6to4, so I'm not sure it is a recent bug or just
I forced it to appear in very last HEAD.

This might be fixed by these two commits:
