[Xen-devel] Issue with MSI in a HVM domU with several passed through PCI devices

Hi,

I have a HVM domU running Ubuntu 12.04. It has several PCI devices
passed through to it (USB controllers, onboard sound, ATI video card
with gfx_passthru 0). It has some issues, the most apparent one with
the sound, which doesn't play normally but repeats the same short
fragment over and over for a while until moving on to the next
fragment. The Xen dmesg prints lots of lines like:

(XEN) [2012-06-18 20:14:16] vmsi.c:108:d32767 Unsupported delivery mode 3

The number behind 108:d varies occasionally.

Since vmsi.c seems to deal with passing on MSI interrupts, I tried
booting the domU with pci=nomsi. This made things work and sound now
plays normally. Not using MSI at all doesn't seem like a very good
solution though.

What makes this happen, and can I fix it in a better way?
