IPv6 (6rd or 6to4) kernel panic



  • Hello,

    I am trying to get IPv6 going on 2.4 Alpha, but as soon as I enable 6rd or 6to4 from the Web GUI, my PfSense instance crashes and continues to boot loop & crash. To get the system stable, I have to boot into single user and remove the PfSense config. If it helps, my instance is setup in a KVM VM using VirtIO for networking and has hardware checksum disabled.

    I had the crash uploaded via the GUI (required /conf/config.xml to be deleted to get the instance booting again), but below you can find a copy of the information:
