The log seems to show that you are very short on memory. The backtraces
come from "page allocation failure", not from any conditions in the
ath9k driver. You have a lot of free swap, so I assume it's the
non-swappable memory. This is also evidenced by lowmem_reserve:
lowmem_reserve[]: 0 0 0 0
I haven't heard of any major memory leaks in ath9k, so I would not blame
it on the driver unless you can show that you don't get that problem
with another driver.
In the future, please send kernel logs produced by the dmesg command.
This will avoid the timestamps from syslogd (especially since you
already have kernel timestamps) and it would ensure that no kernel
messages are skipped by syslogd because of their low urgency.
