The problem is more general und ugly than I thought. I took 2 arbitrary boxes, one behind an Ethernet (A, Kernel 2.6.21, MTU 1500), one behind ADSL (B, 2.4.x, 1492). Established a tunnel, copied a file from site A to B through the tunnel and router A died in the same moment. Out of my feeling this worked fine some kernel releases earlier. As written in this thread before, I see an external need-to-frag-ICMP, no tunnel need-to-frag will be thrown, box freezes. You should be able to reproduce it with any network path with a smaller MTU?!?
