I cannot pass a PCI card w/ a shared IRQ to a domU.

If my PCI card is in a different slot, and gets a different IRQ, it works. 
 But in this one particular slot, it gets an IRQ that's shared with a 
bunch of other bits of gear (USB, firewire, and ATA controller).  With the 
shared IRQ, not only can I not pass the card to my domU, my dom0 freaks 
and dies as well...

Both my dom0 and domU are using the latest xen/master pv_ops kernel and 
I'm using Xen 3.4.2 (for now).  My domU is a pv domain.

I've attached serial output.

Is this a bug in something (kernel or hypervisor) or a known limitation 
with pci passthrough...  I sure hope it's a bug, cause I need to fill all 
my PCI slots with cards that are going to get passed into different 
domUs...  :-/

-Mike
