I'm having a similar problem (a PCI ethernet device that worked under 2.2.7 won't work under 3.0) and I think it might be due to the changes in pci_map_port(). Under 2.2.7 there's some code in pci_map_port() that apparently enables intermediate bridges, but I don't see the same functionality in the pci_map_port in the PCI compatibility code. I've sent some mail to Stefan about this, but he's apparently swamped. If anyone else can take a look at the PCI code and confirm my diagnosis and provide me a workaround or a patch, I'd really appreciate it. It may also be causing you a problem, too. I'd patch it myself, but without a PCI spec, that code looks pretty daunting... - ---------------------------------------------------------------------- Ted Faber faber@isi.edu USC/ISI Computer Scientist http://www.isi.edu/~faber (310) 822-1511 x190 PGP Key: http://www.isi.edu/~faber/pubkey.asc -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQCVAwUBNtYAcIb4eisfQ5rpAQHyGwP/S80mLywaVH9KG3HksXSCHQZiLooGCyPj WlSrpBaCdqDqux9H1B/Kru5iVnrSf/QzuHL8sY9minQtr+wWKT0TTplS8qvFg4Rr f0v3Np1GkgTtXjbw0mjwsrYvAiqnK0yp23CGm4Wnth31Q3zlXhfXakGNlrtuJURb 13gj3Vs865o= =gdkp -----END PGP SIGNATURE----- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
