I just realized that the address may change in different environments.
In previous email chains, I used a cached dump from a Linux
environment running outside the hypervisor.
Sorry for the confusion. Refreshing with a XEN dom0 dump.
The other device I used is a SATA controller. I think I can get what
you are looking for now.
Both a2616 and a2504 are found!
