Ends up in dmesg output like:tg3: tg3_reset_hw timed out for eth1, firmware will not restart magic=00000000Delegating my USB controllers e.g. works flawlessly. You could try getting rid of access control on I/O memory and I/O ports. Modify the Xen definitions of macros ioports_access_permitted() and iomem_access_permitted() to always return 1. Then see if the NIC works. If so, the code in domain0 to work out what resources a given PCI device requires is not working properly for you. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
