Hi,
I'm running 8 stable and I found the system freeze twice so long.
when i try ifconfig wlan0 destroy , the system hang up and freeze, Or I
try /etc/rc.d/netif restart, the same thing happend.
I think the system freeze is because the interface wlan0, I had see the
interface wlan0 would disappear itself!! and I saw "ioctl(SIOCGIFFLAGS)
on wlan0: " message.
I can not found any useful info for that,but i got some strange messages
from dmesg:
