Bug#571603: linux-image-2.6.26-2-xen-686: Dom0 crashes on newer hypervisors if msi interrupts are available
The default Debian kernel dom0 will not boot on
hypervisors >= Xen 3.3 if MSI interrupts are available.
The reason for this is that one of the patches included
in the build (suse-200808...) has an incorrect structure
definition. (It was a structure used at some point during
development, but changed before the 3.3 release. The patch
was a snapshot of development after the initial change but
before the final version.)
The attached patch updates the msi code to the appropriate
(released, stable, forwards-compatible) structure definition,
so that the 2.6.26-xen kernel can boot on future hypervisors
(including the upcoming 4.0 release). I've already tested it
within the debian source build system.
A work-around is to add "pci=nosmi" on the kernel command line.
