The dmesg from a verbose boot may be useful. The "port may not be enabled" line looks to be the most relevant one. >I have no idea WHY it's saying IRQ 19 as IRQ 19 is used by sis0.

It appears that there is an error in /usr/share/misc/pci_vendors. Feel free to write a bug report. The kernel is correctly recognizing it. >Here's the problem.

Probably because your motherboard vendor decided to save a few deci- cents by not bothering to connect up all the available interrupt inputs and just share one. This isn't FreeBSD - it's the copper tracks on your motherboard. --=20 Peter Jeremy --oTHb8nViIGeoXxdp Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (FreeBSD) iD8DBQFFzFVy/opHv/APuIcRAhIRAJ4gPfZyu6HhFWG949N6iEXvIu8NkACfWXQx fp08kijwSA8e+cb3rpmx1zs= =u6IP -----END PGP SIGNATURE----- --oTHb8nViIGeoXxdp--
