Confirmed here, on AMD 64 architecture :
Sep 19 14:20:12 cameleon kernel: [33076.019565] vtund[2020]: segfault at ffffffffaaac40c8 rip 00002aaaaace8872 rsp 00007fffffc1dd10 error 6
I've got a similar config, and I can set the tunnel up, but whenever I try to use it (let's say trying to ping the other side) it crashes.
My kernel is 2.6.15- 27-amd64- generic though, but I guess this won't change a lot.
I'm trying to compile it from the sources to see if I can make it work...
