I sad wrong. minerd was started from cron after reboot immediately and broke SMP, so when I disable minerd from cron and reboot - SMP works fine. I think Andrey Chernov said here the reason http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/163585#reply3 So this bug is alive - on 9.1 and 9.2 x64 releases. I didn't try SCHED_4BSD yet, cause don't wont to use not-generic kernel because of mining only, but for interest I'll try it on one machine on this weekends. _______________________________________________ freebsd-ports@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "freebsd-ports-unsubscr...@freebsd.org"
