No, it doesn't. It crashes kernel once a day and deadly hangs till reboot every 30 min. I've send a bug report, but nobody cares. I use RTL8192CU. It crashes kernel once a month. 31.01.2014, 22:01, Zé Loff zel...@zeloff.org: On Fri, Jan 31, 2014 at 01:50:44PM +, C. L. Martinez wrote:   As

Test it. Both should not load CPU a lot. But that doesn't mean they wouldn't. Write here if notice intense interrupts CPU load. My OpenBSD 5.4 amd64 laptop fail to handle 2 MB/s wifi due to some drivers issues (they load CPU up to 100% interrupts). Additional info about interrupts load would be

Hi. sndiod -r on fails with snd0: rsnd/0: failed to open audio device. All other programs are capable to play sound, but they lock device. aucat -i test.wav -d says it uses snd0. That's strange, sndiod can't open the same snd0 azalia device. Any ideas? Are there any other software mixer working

Hi. I discovered high CPU0 interruptions load (amd64) in various cases. wifi (athn, urtwn): up to 100% at 2 MB/s download. Usually 50%. Grows faster then linear with net load. Sometimes system freezes for about a minute. Web speed tests consume significantly less CPU then wget/firefox/ktorrent
