You wrote 30 =E0=EF=F0=E5=EB=FF 2013 =E3., 8:53:00: AC> Any follow-up with the latest stuff in -HEAD? I'd like to see if the AC> hardware queue is behaving how I think it is. Sorry, was busy yesterday. Sources: r250041, TDMA is enabled in kernel config. Warm-up: 120 seconds of TCP, throughput osculate between 50 and 100Mbit/, several BAR resets, no hangs. Test: 600 seconds of UDP. Throughput is 20Mbit/s. Hang on ~327s. traffic generator stopped, single "forced bstuck" helps. Log attached. Please, note: low throughput for UDP on these revisions. It was not so on older revisions, before all this additional debug stuff was added, latest good I tried was something like r249333, and I don't remember about r249767 (but I could try, firmware image is not removed, and I don't have images between r249333 and r249333). --=20 // Black Lion AKA Lev Serebryakov <lev@FreeBSD.org> ------------0121790D21751CE77--
