| Hi!
|
| RELENG_7 from October,9 ( em card )
| Also repeatable on another box with RELENG_7 from last Saturday. ( xl and nfe )
|
| Boot single user or remount readonly.
|
| ifconfig vlan1 create vlan 1 vlandev xl0
| ifconfig vlan2 create vlan 1 vlandev xl0
|
| instant panic.
|
Now found time to repeat with serial console:
%/sbin/ifconfig vlan1 create vlan 1 vlandev xl0
%/sbin/ifconfig vlan2 create vlan 1 vlandev xl0
