Yeah, from those logs it looks OK.  Was that a "coaxed" Xen boot?  It
certainly looks like lots of interrupts are being received properly
(drives detected, usb probed, etc).

Also, for a more direct comparison, what happens when you boot native
with pci=nomsi?  I assume it will work, but it will make the logs
directly comparable; or maybe the system just doesn't work without MSI?

Is your initrd set up right?
