maybe I should report to ath9k-devel list, but I think it might be the problem of OpenWrt configuration, caused by using the module minstrel_ht. the reason I try minstrel_ht is I could only get around 50Mbpsthroughput rate by using ath9k for my AR9280 card. some developer saidthe low throughput is a known problem for ath9k on IPX4xx platform, itwas kind of optimizing work. I still cannot see any light on thisproblem since last year. I sawthe crashing on several trunk since OpenWrt r20294, till r20851, yes itwas caused by iperf test while it was just nice by ping test. topology: PC1 - STA - AP - PC2 iperf/ping was form PC1 to PC2, the crash happened on both AP and STA, see attachment for the log, Thank You !!
