AH, thats a shame to hear - was hooing it had worked OK for you! > Here is a test case. > https://lists.freebsd.org/pipermail/freebsd-stable/2018-February/088433.html Will give that a try next week - when remote form the box I dont want to crash it, so no such tests at the weekend, but hen I am back will see. The lockup from Thursday was aan idle-lockup, and that hasnt happened since I chnaged the BIOS settings. May reenable those one at a time to see if any single one is reposible, unless anyone has any insight. Much hunch would be that SMT may be OK to re-enable as tat has nothing do do with loading, whcih the other two do. cheers, -pete. _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
