Hi all,

newest -HEAD panics to KDB when setting up wlan0:

   can't re-use a leaf (wlan0)!
   panic: bpfattach tscfgoid
   KDB: enter: panic

Some more infos:

FreeBSD 10.0-CURRENT (GENERIC) #3 r228993: Fri Dec 30 17:37:25 CET 2011
...
ath0: <Atheros 5413> mem 0xd4000000-0xd400ffff irq 17 at device 4.0 on pci5
ath0: AR5413 mac 10.5 RF5413 phy 6.1
ath0: 2GHz radio: 0x0000; 5GHz radio: 0x0063

wlan-/net-related stuff from rc.conf:

wlans_ath0="wlan0"
create_args_wlan0="wlanmode hostap country DE"
ifconfig_wlan0="inet 192.168.100.1 netmask 255.255.255.0 up channel 5:g"
hostapd_enable="YES"

pf_enable="YES"                 # Enable PF (load module if required)
pf_rules="/etc/pf.conf"         # rules definition file for pf
...

What does "can't re-use a leaf" mean? Did I miss something?

Cheers

Martin
