Added linux-net as I used a wrong address in the original mail.
I am able to trigger this kernel panic when a client copies data using
SCP to another client using the same AP:
client_1 <---wired---> AP <---wireless---> client_2
The panic happens after transferring around 30-40 MB of data.
The AP behaves stable with normal traffic (HTTP, HTTPS, IMAPS, text SSH).
The AP is Asus WL-500gP, it's a MIPS platform, running 2.6.31.1 kernel,
hostapd v0.6.9.
I can reproduce the issue reliably.
Let me know if you need more info here.
