In the past I used Debian Etch Xen 3.2-1 with the Bastian Blank (waldi) kernels. I noticed some problems with MSI handling in that combination. As Debian kernels and Xen builds created problems for me with respect to powermanagement (time went backwards), I changed to the Xen kernel. So that was the basis of my guess, when I read that someones using a Debian kernel and an MSI based error message occured. By the option - as explained - you switch that off and use GSI instead. For me, I will check in one of the next steps, whether I can use my 4th PCI slot, that up to MSI support shared GSI IRQ with the PCIe slots that now have their own MSI.
