Aha! I installed 2.6.21 from backports and it works. Thanks very much.IPv6 under 2.6.21 is buggy (at least the upstream version, don't know about the Debian kernel). Please use 2.6.20 or 2.6.22, both seem to be fine. http://lkml.org/lkml/2007/5/28/299
It is not that simple. Upstream kernel versions have 4 numbers, but Debian kernel versions use only the first 3 numbers.
Bug #8349 was caused by a patch introduced in upstream 2.6.20.5 and 2.6.21. According to the changelogs it was fixed in upstream 2.6.20.14, 2.6.21.5 and 2.6.22.
So I believe that a 2.6.20 Debian kernel may contain the bug and a 2.6.21 Debian kernel may not, depending on the 4th-number of the upstream version there were built from.
