When I set two PC with Atheros AR2413 in mesh mode, they can find each other, then I tried to ping each other, after send 10-12 ping packets, the PC will hang up, below is the dmesg output, I suspicion this bug is the same as this one http://marc.info/?l=linux-wireless&m=121731102709834&w=2, but don't know if anyone has solved it?
