[DragonFlyBSD - Bug #2565] "ifconfig ix0 up" panic

[Francois Tigeot via Redmine]

Issue #2565 has been updated by ftigeot.


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.

Just installed a new nic - 10G 82599 dual port. 

The system recognizes the ixgbe device and shows up ix0 and ix1. 

Whenever a "ifconfig ix0 up" or "ifconfig ix1 up" is issued, the system crashed -
