# Now we can start discussing ACPI PCI vs. legacy PCI :)
DSDT in ACPI BIOS on Supermicro P3TDE6 has obviously wrong _BBN value,
but previous kernel can fall back to legacy PCI bridge probing even if
PCI bridge probing by ACPI is failed.

I think that previous probing system is much more robust and safer
in many cases, especially buggy ACPI BIOS.
John, can we have previous PCI probing system again?

Thanks
