Description

Device: Asus WL-500gP + Atheros AR5413 (Ath5k)
Arch: brcm47xx
Branch: AA
Rev: r36936

Hi,
I'm having trouble with several routers like the one above. I think it happens when several wifi clients are connected simultaneously.
I also tried trunk but the routers keep rebooting.

Hello again,
I got another reboot but it looks a bit different. Maybe the 1st ones is not exactly related to ath5k.

Replying to hauke:

Is there an easy was to reproduce this?

Unfortunately not. I had to wait a few days before capturing the error. I had to leave the serial port console open on a PC to be able to capture the logs.
ATM I'm not using that router. I replaced it because of the instability. So I will have some difficulty to perform tests on the same environment but I can try if necessary.

Could you try a recent trunk build please and report back if this "Unhandled kernel unaligned access" problem still exists?
