Issue #2355 has been updated by Francois Tigeot.

I switched the main ethernet interface from bce0 to ix0:
  ifconfig bce0 -alias xxx
  ifconfig ix0 192.168.x.x/24

At this point, the default route was gone
As soon as I typed route add default to add it again, the system crashed
Bug #2355: panic: rtrequest1_msghandler: rtrequest table error was cpu4, err 17

Author: Joachim de Groot
Status: New
Priority: Normal
Target version: 

I experimented with wlan and dhcp and had some trouble to get it to work.
To start from scratch, I've deleted the generated interface wlan0 after running /etc/rc.d/netif stop.
At some point after running /etc/rc.d/netif start again this panic occurs. This is reproducible.
