Hiya
There seems to be a regression, I've recently bumped into this bug again.
(2.6.9-fc3-latest-thing, I didn't see anything relevant in latest Linus bk).
It did work for some time ago, since them my ipv6 configuration has changed
and I've updated the kernel quite a bit.
if [ "$device" != "sit0" ]; then
if ipv6_exec_ip tunnel show $device 2>/dev/null | LC_ALL=C grep -q -w "ipv6/ip"; then
ipv6_exec_ip tunnel del $device
is what triggers it, tunnel del gets stuck with a refcnt of 1, device is no
longer in /proc/net/dev. Tunnel is run on top of PPPoE and it's a dynamic
sixxs.net aiccu thing. IPv6 forwarding is on.
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=282023 seems to be related
too.
