[Xen-users] Intel Quad NIC made visible in guest -> system crash

[Alexander Menk <alex.menk.lists2@xxxxxxxxxxxxxx>]

Hi!

we have two Intel Quad Nic 82576, PCI ID 8086:10E8 and use the igb
driver 1.3.19.3 on Debian 5.0.1.

I used the pciback.hide XEN kernel parameter and made on of the NIC's
interfaces available in a DomU.

Now, when I am starting the VM, the system crashes (log attached)

I also tried to boot with the irqpoll option - the Interrupt Disabled
message still appears when I try to start the VM.

Is that a serious driver problem or something that is easy to fix?

Best Regards,
  Alexander
