If you boot Xen with iommu=debug, do you see any messages on the Xen console? My test boxes also use AHCI, but the chipset is not exactly the same (mine is ICH8, yours is ICH10). Do you do anything specific to trigger the timeout, or just leaving Dom0 in an idle state also triggers this? Could you switch to the Xen console and post the output of the "i" debug key when this happens? Also, you can try to play with the AHCI driver sysctls, to see if some of them have any effect. I would recommend trying to disable MSI interrupts (hint.ahci.X.msi=0) and power control (hint.ahcich.X.pm_level=0).
