But it looks like PnP ACPI is also reserving those memory ranges: Aug 30 14:08:02 alcor kernel: pnp: 00:09: iomem range 0xdfefd000-0xdfefd3ff has been reserved Aug 30 14:08:02 alcor kernel: pnp: 00:09: iomem range 0xdfefe000-0xdfefe3ff has been reserved Which I very much doubt it should be doing, the BIOS doesn't need to reserve PCI BAR ranges in the ACPI tables. This sounds like a BIOS bug. You might want to check for an update from Supermicro. -- Robert Hancock Saskatoon, SK, Canada To email, remove "nospam" from hancockr@nospamshaw.ca Home Page: http://www.roberthancock.com/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
