But you are using the acpi driver, not the pciexpress > driver, is that what you mean to do? I was hoping that I could use the ACPI driver since the pci express native one will not work on the nvidia CK804 which is the real reason I am trying out pci express hotplug. But, it seems using the native driver does make the Intel board happier.

The driver loads and works. But, I would like to get the ACPI driver working... -tduffy --=-2JSY2E+naI/7JA1EHOpT Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (GNU/Linux) iD8DBQBCLejLdY502zjzwbwRAjC/AKCLoFi6ma13V8V1Kusl6do60cFONgCdFt5E MJtFlCcxPmb2/bQ7d0V9/rc= =Wamp -----END PGP SIGNATURE----- --=-2JSY2E+naI/7JA1EHOpT-- ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
