Hello,

I have an issue with my XEN system. I suspect that it might be a bug, but I'm no linux expert, so I don't know. Here is my problem: I have an ASUS P7P55D-E Premium motherboard, and a Western Digital Caviar Black SATA-III 1TB hdd. I am trying to use AHCI. The dom0 is an Arch Linux. The dom0 boots fine until Intel VT-d is enabled in the BIOS. When I enable it Arch Linux still boots fine, but XEN with the Arch Linux Dom0 fails to detect the hdd (the /dev/sda node doesn't exist), and drops me into a recovery shell. I have upgraded to the latest BIOS version, but it still fails.
My XEN version is: 4.0.1
My Arch Linux dom0 kernel version is: 2.6.34-dev (2.6.32 also fails)

(Probably) relevant lines from dmesg:
