Hi,

I found a suspend/resume bug.
Kernel 2.6.32-wl-45997-gf02c03a master-2009-12-07

To reproduce:
- connect to 2G network (my office)
- pm-suspend
- resume (at home, wpa_supplicant.conf only has 5G home network)
- laptop only scans 2G, never sees 5G AP
- workaround: 
    /etc/init.d/network stop
    rmmod bla bla bla
    modprobe ath9k
    /etc/init.d/network start
- now laptop reconnects


Thanks for your work folks!
Felix
