I believe this is a BIOS bug. And preferably, Linux should complain about it. Since we know it is going to cause problems, and since we know it does happen, we should be raising a ruckus about it in the kernel log (and probably fixing it to min(path) while at it)... Is this something that should be raised as a feature request with the PCI/PCIe subsystem? -- "One disk to rule them all, One disk to find them.
