Hello! I'm trying to figure out what's wrong with the pv_ops dom0 kernel/patches [1] causing at least ata_piix and ahci drivers to fail to work. There was legacy IRQ enabling problem earlier with the pv_ops dom0 patches, which pretty much prevented the disks from being detected.. but that got fixed. It could still be something related to Xen/dom0 irq handling.. I'd be glad if someone could take a look at this 2.6.29-rc3-tip pv_ops dom0 kernel boot log and comment about _possible_ causes for such behaviour of ata_piix and ahci: http://pasik.reaktio.net/xen/pv_ops-dom0-debug/pv_ops-dom0-bootlog-11-xen331-linux-2.6.29-rc3-atadebug3.txt In that testing box I have just one IDE hdd attached to ata_piix controller, the AHCI controller doesn't have any disks attached. The exact same kernel works OK without problems on baremetal without Xen hypervisor.
