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:

commit edb666f07e ("xfrm6: Properly handle unsupported protocols") commit 61622cc6f2 ("xfrm4: Properly handle unsupported protocols")
