My pc doesn't hang after I modified re. The configuration of my pc is core2quad intel cpu with 2GB memory. It doesn't hang with both of four core configuration and sigle core configuration. I did bi-directional netperf test. It ran without hang. Would you give me the latest re.c ? -masa >Cheers, > >Steve _______________________________________________ driver-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/driver-discuss
