Ok, just to publicly state that the Intel board apparently was not attaching to core0. I saw the failure and assumed that it was cpu related and would be the same as the Asus board.

Ok, the patch is applied on the Asus board and it now appears to be working correctly. I've re-enabled powerd now, so we will see how that goes. When it was only attaching to core0 the board would hang at times with powerd enabled. robert. > Thanks! --=20 Robert Noland <rnoland@FreeBSD.org> FreeBSD --=-qrTBfmH6pEsSotQ4jCoC Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.11 (FreeBSD) iEYEABECAAYFAkn/FWoACgkQM4TrQ4qfRONOcwCfaBPVIGBgyY7RqgQ3wKRsNL5Y 5qYAnjJS+Bl/6ZNo7VM7YK7hDxgoyklw =wavN -----END PGP SIGNATURE----- --=-qrTBfmH6pEsSotQ4jCoC--
