    Default IPv6 Problem in Kernel 2.6.24-10-pve

    I install Proxmox 1.5 and install kernel 2.6.24-10-pve on a dell 1950 server, I want the container to support IPv6, so I add following lines to /etc/sysctl.conf:
    net.ipv6.conf.all.autoconf=0
    net.ipv6.conf.all.forwarding=1
    net.ipv6.conf.default.forwarding=1
    net.ipv6.conf.default.proxy_ndp = 1
    net.ipv6.conf.all.proxy_ndp = 1
    then I use sysctl -p and use the following command to add ipv6 address to container:
    vzctl set <ct_id> --ipadd <ipv6_address> --save
    The container can support IPv6 commuincation normally.
    But when I stop the container or reboot HN node, I get following error messages on the console:

    the last line will repeat again and again. I have to reboot the HN node.
    When I install kernel 2.6.24-9-pve, there is no such probem.
    Is there bugs with IPv6 in kernel 2.6.24-10-pve?

    2.6.24-10-pve include a ipv6 fix - obviously there is something wrong with that.

    Hi,
    I've got the exactly the same Error with Kernel 2.6.24-11-pve on an Hetzner EQ4 Server.
