Subject: what does this mean

I tried the 2011 03 26 compat-wireless and it gives this error when I
try a scan (it finds some networks but I know there are more).

sudo iw dev wlan0 scan | grep -i ssid

ath: timeout (100000 us) on reg 0x9c20: 0x00000000 & 0x00000001 !=
0x00000001
ath: Could not kill baseband RX

this is the default timeout in hw.h
#define AH_WAIT_TIMEOUT 100000 /* (us) */

may be you can try increasing the timeout specifically for this

diff --git a/drivers/net/wireless/ath/ath9k/ar5008_phy.c

}

and this is also there in ar9003_phy.c

James, this is a fatal error.

Is there anyway to increase the timeout or reset the hardware without
rebooting?
