I have some problem about setting the PCI passthrough NIC with Broadcom NetXtreme II BCM5716 Ethernet controller

I strictly followed xen wiki

My configuration is pvops 2.6.32.26 dom0, pvops 2.6.32.27 domU kernel, xen 4.0.1 official release, Intel core i7, 64bit

no hvm, no IOMMU/VT-d, just pv guest.

I could success PCI passthrough by using domU with 2GB~3GB memory.

(Strangely, I could not see the assignable pci lists when xm pci-list-assignable-devices command,

But it seems to work well even when the passthroughed domU is used as IDD)

However, When I allocated to above 4GB memory to domU,

domU device driver complain with below messages, and it does not work well

=======

Broadcom NetXtreme II Gigabit Ethernet Driver bnx2 v2.0.2 (Aug 21, 2009)

bnx2 0000:00:00.1: device not available because of BAR 0 [0xdc000000-0xddffffff] collisions

bnx2 0000:00:00.1: Cannot enable PCI device, aborting.

bnx2: probe of 0000:00:00.1 failed with error -22

=======

Is there anyone who suffer from this??

Thanks.
