thanks for the hint. have you verified that this behavior only occurs on systems with a dual core cpu? is it possible to disable one core and see if the behavior is also reproducable then? i'd like to test this, but i don't know the magic juju to disable one of my cpu cores. :( cheers. alex > > -- > Bruce Cran -- a13x _______________________________________________ freebsd-bugs@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
