[iPAQ] IPAQ 5550: Second WLAN device appears after wake-up

Hello there,

I just ran into a strange problem with the WLAN driver on my IPAQ 5550
(actually on both 5550 I use right now):

WLAN works fine with the at76c503 after bootup, iwconfig only shows
one wlan device (wlan0), which gets configured by the networking
init.d-script.

As soon as the IPAQ comes back up from suspend mode however, a second
wlan device (wlan1) appears (only listed by iwconfig though) and wlan0
stops working (i.e., any communication over that device ceases).

This is my 'dmesg' output:
usb.c: USB disconnect on device 2
hub.c: USB new device connect on bus1/1, assigned device number 3
at76c503-fw_skel.c: using compiled-in firmware
at76c503.c: $Id: at76c503.c,v 1.69 2004/09/05 14:07:09 jal2 Exp $
compiled Oct 1at76c503.c: firmware version 1.103.5 #164 (fcs_len 4)
at76c503.c: device's MAC 00:02:8a:de:f9:bf, regulatory domain MKK1
(Japan) (id 6at76c503.c: registered wlan1
at76c503.c: wlan0: lost beacon bssid 02:00:b2:6c:e5:00
at76c503.c: wlan0: set_card_command(CMD_RADIO) failed: -110

I am using kernel 2.4.19-rmk6-pxa1-hh37 compiled (today) by
OpenEmbedded. Any hints on how to avoid this would be appreciated -
especially since I haven't found a way to get rid of wlan1 except by
rebooting?!

TIA,
Oliver
