Hello, please find the following kernel crashlog from the latest snapshot of ar71xx (2011-08-16, r28007) running on an Ubiquiti NanostationM5 (full crashlog attached).
Device was configured as routed wifi client (with NAT). Wifi association in HT20 mode and using MCS14~MCS15 for tx. 64 bytes packets upload traffic (eth0 -> wlan0) at maximum pps for the platform. Traffic is routed and NAT'd ok at 4Mbps to 6Mbps for a few minutes before crashing. While routing, CPU is loaded at something like ~90% irq and nothing else. The call trace is not explicit as is. Is it needed to compile another image with debug symbols enabled to understand the call trace?
