I've filed a new bug for this problem: 6446729 "cpu 1 failed to start" when TSC counters are not in sync http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6446729 To fix the problem, I've moved the tsc clock synchronization code for the slave cpus in mp_startup() up a few lines, so that the gethrtime() call [via cmn_err() -> gethrestime() -> pc_gethrestime() ] runs when the tsc clock delta is initialized. (see the bug report) The ASUS N4L-VM mainboard doesn't hang any more during mp cpu startup. Comments?
