Andy,

I am a bit confused , trying to follow up the thread running by Todd and you.
Are this messages coming up on your box ?

Boris,

It does support ahci, and it works with other kernels, the problem is
that I am testing pvops dom0 kernel and it does not work with that.

I included the same drivers I use successfully with other kernels, the
problem is with the pvops dom0 kernel.
