Double fault panic with Charter 6rd and latest amd64

  • I just updated to 2.1-BETA1 (amd64) built on Sat Mar 23 22:05:35 EDT 2013
    FreeBSD 8.3-RELEASE-p6, the system repeatbly crashes when initializing the WAN interface.  After removing the IPv6 6rd config, it boots and works fine.  I can provide a crashdump if needed.



  • I encountered probably the same problem:
    After initializing wan and several (vlan) devices pfsense hangs a short time (20 seconds), then the device starts up, and again after about 20 seconds the machine reboots.

    I could not find out the reason and had to roll back a full backup from the console.

  • Forgot to mention that re0 is:
    re0: <realtek 8169sc="" 8110sc="" single-chip="" gigabit="" ethernet="">port 0xe800-0xe8ff mem 0xfebdfc00-0xfebdfcff irq 18 at device 4.0 on pci5
    re0: Chip rev. 0x18000000
    re0: MAC rev. 0x00000000</realtek>

  • In my case, it was an emulated em0…
    It's likely to be rather an ipv6 stack error

  • Hi guys,

    Take a look at this post:,59461.msg325150.html#msg325150

    It seems there have been some problems with 6RD in general since late January for several users. Personally I'm still on the Jan 18nd snap since that's the last one that worked with my Charter connection.

    I have a ticket open here:

    CMB, one of the devs, says that things will be fixed in the Sunday (or next) snap….I don't know if that means they are backing out the change they made that causes the fault or if they have a solution for the overall 6RD problem.


  • Thanks for the information Will, I'll sit tight :)
