ath5k phy3:failed to wakeup the MAC chip

[esolve]

I'm using a plug-in D-LINK AirPlus DWL-G650 wireless card, after I plug it in the socket, it shows

ath5k phy3:failed to wakeup the MAC chip

and for "ifconfig" command, it shows:

wlan1 Link encap:Ethernet HWaddr 00:1C:F0:14:32:5E
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)


previously, it worked fine, so what is wrong with this failure?
