Obviously, this is somewhat inconvenient. :-) The device in question is a PCI-X Neterion 10gbps card. The output from the kernel when the device driver is loaded is: Copyright(c) 2002-2005 Neterion Inc. xge0: mem 0xd8300000-0xd8307fff,0xd8400000-0xd84fffff,0xd8308000-0xd83087ff irq 25 at device 1.0 on pci129 xge0: Device is on 64 bit PCIX(M1) 133MHz bus If there's more information I can provide I'm happy to do so, just let me know what's needed. Is there a way I can disable vpd support at boot-time in some form -- i.e., via a tunable? It would be very useful if these machines worked.
