[Xen-devel] Re: SATA pass-through woes

A quick addendum to this:

I've tried with both PVOPS (2.6.31.13 and 2.6.32.26) and 2.6.18
kernels. For 2.6.18, the SATA driver doesn't work, so I use the PIIXn
regular ATA IDE driver (in the BIOS I have the SATA set to export the
device in IDE mode rather than AHCI, as I don't think I can pass AHCI
devices through).

The issue is the same in both (constantly reading in 0xff from the
status port and SRST failing and eventually giving up).
