RE: [Xen-devel] Re: VT-D On An Asus P5E-VM DO Motherboard Not Working, Xen 3.4.1

[Tim Moore <timothy.moore@xxxxxxxxxxx>]

If I recall from my testing of an ASUS P6T (before I bought an Intel board) 
enabling/disabling legacy USB, Firewire and the External SATA controller 
changed the RMRR ranges and produced different results ... suggest try disable 
legacy USB and Firewire to see.

Your BIOS has declared an RMRR range of cf600000-cfffffff, compared with
Sander's invalid d0000000-cfffffff. So the BIOSes must be different, or
differently configured.
