>Description:
Laptop HP nc6400 / 1GB RAM, equiped with wpi0 '3945ABG Wireless LAN controller' and bge0 'BCM5753M NetXtreme Gigabit Ethernet PciXpress'.

Home internet is provided by wireless Linksys router ( LAN and WAN links use the same pool of 20 IP addresses ). bge0 is linked by ethernet cable directly to the Linksys router and configured using DHCP, wpi0 is not configured at all. After execution of 

# ifconfig wpi0 inet 10.155.0.1 up

in a few seconds later the system reboots.

First time observed when requested DHCP on wpi0 after bge0 already has assignment from the same very DHCP pool.


>How-To-Repeat:
Home internet is provided by wireless Linksys router ( LAN and WAN links use the same pool of 20 IP addresses ). 

bge0 is linked by ethernet cable directly to the Linksys router and configured using DHCP, wpi0 is not configured at all.

# ifconfig wpi0 inet 10.155.0.1 up
