I'm using this script to replace my development modules...
jonsm...@terra:/home/linus$ cat copy
sudo cp drivers/ieee802154/*.ko /lib/modules/2.6.35+/kernel/net/ieee802154
sudo cp net/ieee802154/*.ko /lib/modules/2.6.35+/kernel/net/ieee802154
sudo cp net/mac802154/*.ko /lib/modules/2.6.35+/kernel/net/mac802154
sudo killall izattach
sudo rmmod serial
sudo rmmod mac802154
sudo rmmod ieee802154
sudo rmmod af_802154
sudo modprobe serial
sudo izattach /dev/ttyUSB0
sudo iz 6lowpan wpan-phy0
sudo ip link set wpan0 address de:ad:be:af:ca:fe:ba:be
sudo ifconfig wpan0 up
sudo ip -6 address add aaaa::1/64 dev wpan0
There is a race condition during the module unload process....
I think what is happening is that you are blocking inside
ieee802154_unregister_device(). While that thread is blocked another
thread comes in and makes a new device. ieee802154_unregister_device()
exits and hits the BUG_ON in ieee802154_free_device() because it is
expecting the list to be empty.
