It looks like it is the kernel that sets this bit because we have never set it in any of our drivers, yet on the intel boxes it gets set. Why would this bit not be set when the chassis is connected to an Opteron. We are running 32-bit mode BTW. I am using a 2.6.11.9 kernel. Is this a motherboard problem or could this be a kernel problem?
If your device needs to bus master you need to call
pci_set_master(pci_dev). The bus mastering setup prior to that really
depends on the BIOS and phase of the moon.
