Xen devel - Oct 2005 - [PATCH] fix bugzilla 89 x86_64 linux won''t boot on hardware with sata drives

changes in the linux patch 2.6.12 -> 2.6.12.5 in drivers/acpi/pci_irq.c 
stopped x86_64 linux from booting under xen on machines with SATA 
drives. This patch undoes only those changes and restores the previous 
functionality.

Gulp. Is this true on native too, or is it provoking a Xen bug?

That patch to pci_irq.c is also included in 2.6.12.6, and even 2.6.14, 
so I guess this reveals an x86_64 Xen bug. Particularly if it doesn''t 
affect xen-i386 builds.

Native 2.6.12.5 kernel *with* pci_irq.c patch and same configuration 
(sans Xen subarch) runs good on bare metal.

This doesn''t help x86_32 SMP which can''t find SATA devices. 
I''ve
confirmed that 2.6.12, and 2.6.12.5 native boot fine.
