I believe that the failure is because the bridge is seen in the PCI register scan, but not in the ACPI AML. Because it's not in the AML, the acpi_pcib driver vetos the attach. I believe that if the machine was booted with ACPI disabled, all of the bridges+buses+devices would be seen regardless of what slots they are in. > > Scott If anyone is interested, I think I can bring up a DL380 g4 so someone can fix it, if there is interest. Probably got even a SmartArray or other PCI-X card that can be plugged in. -- Regards, Ulf. --------------------------------------------------------------------- Ulf Zimmermann, 1525 Pacific Ave., Alameda, CA-94501, #: 510-865-0204 You can find my resume at: http://www.Alameda.net/~ulf/resume.html
