Hello,

Couple of months back when we were testing xcp 0.1.1 and pci passthrough we ran into issues when pci-passthrough enabled device shared interrupts with another controller(in our case interrupt was shared between ide controller and our nic). At that time Ian Campbell suggested backporting event-channel changes from pvops to 2.6.27 kernel. Have two questions related to this

1. I am thinking of porting the changes now but wanted to check if it has been addressed?

2. Will shared interrupts be a problem for pci-e slots as well?

Thanks
-Ritu
