Re: [Xen-users] passthrough issue resulting in device not accepting address 4, error -110

Searching - after letting the domu run for a while - for issues showing up later on in dmesg

...

Adding as suggested irqpoll to grub actually did the trick - everything started working, but from my understanding "irqpoll" is used for diagnostics.

What would be my next step or have I misunderstood the purpose of adding "irqpoll" to grub?

Cheers

I am trying to passthrough 2 identical pcie cards to domu. Individually it they both work fine, but passing them both through at the same time results in one card not working

Currently xen 4.3.2 (kernel 3.2.0-4)

The cards are 2 dvb tuner cards but act as if they are usb hubs.

from dmesg from domU (debian wheezy 7.8):

I have found a few similar issues but without any solutions.

Hope some can help.

Cheers
