The oops is happening at the last line here:

00003d50 <ipoib_mcast_sendonly_join_complete>:
    3d50:       55                      push   %ebp
    3d51:       85 c0                   test   %eax,%eax
    3d53:       89 e5                   mov    %esp,%ebp
    3d55:       57                      push   %edi
    3d56:       56                      push   %esi
    3d57:       53                      push   %ebx
    3d58:       53                      push   %ebx
    3d59:       89 ce                   mov    %ecx,%esi
    3d5b:       8b 89 b4 00 00 00       mov    0xb4(%ecx),%ecx

ecx holds the third parameter of ipoib_mcast_sendonly_join_complete, namely
mcast_ptr, so it seems the oops is happening when doing

        struct net_device *dev = mcast->dev;

Now the question is why this callback is getting passed an invalid mcast_ptr.
