Ok, lets try another test... There is a scanpci util in the libpciaccess port. We don't install it, but it does get built. Build the port and run scanpci -v as root from the console.

See if that is able to trigger the issue. robert. > thanks, > BMS > _______________________________________________ > freebsd-stable@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-stable > To unsubscribe, send any mail to "freebsd-stable-unsubscribe@freebsd.org" --=20 Robert Noland <rnoland@FreeBSD.org> FreeBSD --=-pDhaORuYHyDjB+7pVlxu Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.10 (FreeBSD) iEYEABECAAYFAkmRGZEACgkQM4TrQ4qfRONIFwCfUt7MWo2OQIIdIjeqxwO4XIeS dIkAn2mw2zrU/0/PClUYR+u92nSoqQ75 =lgzg -----END PGP SIGNATURE----- --=-pDhaORuYHyDjB+7pVlxu--
