debug logs

Here are two dmesg outputs on each kernel after I do modprobe ath9k debug=0xffffffff and iwlist wlan0 scan | grep SSID

kernel-2.6.36.4 is good and returns ~15 APs and associates to my AP htp://lockie.ca/test/dmesg_good.txt.bz2

but kernel-2.6.38.5 is bad and returns ~0-3 APs and does not associate to my AP

Maybe someone can see something.
