Just to make sure I understood this correctly.. Does this happen with
just a single association station (your laptop)? What are you referring
to with a "session"? Just another program using network (i.e., no new
wireless associations, etc.)? As far as the ath9k driver is concerned,
new applications (e.g., new TCP connection) should not really matter
much.. If you have IEEE 802.11n enabled, could you please run a test
with it disabled to make sure this is not related to frame aggregation?

As far as getting any output from the system is concerned, the next step
could be to see if NMI watchdog would be able to provide any help.
Please take a look at Documentation/nmi_watchdog.txt in the kernel
source code and see if you could use that on the AP to get some output
when the system hangs (running without X on console to make sure you see
the output).
