D-Link DCF-660W and wlanctl-ng causes kernel panic

Hello,

I have a D-Link DCF-660W card plugged in a PPC 2.6.12 kernel with
wlan 0.2.3 and it panics every time.  I disable /etc/pcmcia/wlan-ng script
and manually run

wlanctl-ng wlan0 lnxreq_ifstate ifstate=enable

and sure enough, the kernel panics:

Kernel panic - not syncing: Must restart system to assure recovery

Kernel modules prism2_cs, p80211, pcmcia loaded ok, ifconfig -a shows a
wlan0 interface.
Basically, everything seems to be happy until I try to enable wlan0.

Any clue to help me debug this problem would be much appreciated.
