Ah! Thank you, yes, that fixed it: FreeBSD/SMP: Multiprocessor System Detected: 80 CPUs FreeBSD/SMP: 4 package(s) x 10 core(s) x 2 SMT threads Given the number of "CPUs" in some top end processors (up to 30 per socket), a limit of 64 is starting to seem low. Is it worth doubling it to 128? Or even higher? It'd be nice to be able to use a stock kernel with freebsd-update at least. Anyway, thanks for your help Alan, at least my system is working fully now :-) Tim. -- Tim Bishop http://www.bishnet.net/tim/ PGP Key: 0x6C226B37FDF38D55 _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
