oops, the cut and paste messed up. try again..

Could you describe a bit your setup ?

- What variant of 82599 is this ? base-T ? fiber ? SFP+/copper ?
- What sort of host is it plugged in ? What is the operating system version ?
- Are you running IPv6 on the network the ix interface is plugged in ?

Is this the complete backtrace by the way ? the "..." at the end give me some doubts.

- This is a 82599EB, using 10Gbase-Twinax.
- HW platform is a Intel DZ77BH-55K, i5-3570K CPU, 32GB Ram, running Dfly 64bit 3.4.1
- Generic kernel (with IPv6) was used with the panic.

The reason for the "..." is that the screen was captured with a phone and re-typed, as follows -
