Hi Moritz,
I just tested with latest Squeeze (and latest kernel). Same problem, another state though:
[1046073.600266] Kernel unaligned access at TPC[104ea7fc] copy_to_user_state+0x54/0x9c [xfrm_user][1046073.715755] Kernel unaligned access at TPC[104ea7fc] copy_to_user_state+0x54/0x9c [xfrm_user]
It happens as soon as there's traffic over the tunnel.
Kernel:*2.6.32-trunk-sparc64 #1 Sun Jan 10 23:56:57 UTC 2010 sparc64 GNU/Linux
Regards,Sebastian

The next release of Debian (6.0, code name Squeeze) will be based
on 2.6.32. Please test the current 2.6.32 from unstable/testing and tell
us whether the problem persists. If so, we should report it upstream
to the kernel.org developers.

The 2.6.32 kernel is available from packages.debian.org and can
be installed in both Debian stable, testing and unstable
installations.

Thanks,
