[Xen-devel] ata_piix SATA driver broken under Xen?

[Adam Nielsen <adam.nielsen@xxxxxxxxx>]

Hi all,

I've been trying to boot Linux 2.6.16.16 as dom0 for a few days now but
I can't work out how to get XenLinux to recognise my disk.  It's
looking like a bug in Xen, as booting the same version of Linux without
Xen works fine.

Does anyone know of any issues with the ata_piix (Intel ICH5/6) driver
and SATA disks?  Has anyone got this configuration going?

Boot messages follow.  This is with Xen 3.0.2-2.

Thanks,
Adam.
