Hi again,
I managed to use git bisect to pinpoint the exact commit that causes
my laptop to freeze:
53bc7aa08b48e5cd745f986731cc7dc24eef2a9f is the first bad commit
commit 53bc7aa08b48e5cd745f986731cc7dc24eef2a9f

ath9k: Add support for newer AR9285 chipsets.
This patch adds support for a modified newer version of AR9285
chipsets.
Signed-off-by: Vivek Natarajan <vnatarajan@xxxxxxxxxxx>

I'm CC'ing this to Vivek also.
The chipset is reported as AR9285 rev 01. by lspci (I previously
stated it was rev 2, this is wrong).
While bisecting I found a reliable way to reproduce the freeze. I
devised a script to continuously bring the interface up and down:
COUNTER=1
while(true); do
sudo ifconfig wlan0 up &&
sudo ifconfig wlan0 down &&
echo $COUNTER &&
let COUNTER=COUNTER+1
done
On stable kernels I let it run to around 150. On unstable kernels it
reached at most 8.
