PCI failure with virtual machine (new as of the past few days -next)

[Alan Cox <alan@xxxxxxxxxxxxxxxxxxx>]

8139cp: 10/100 PCI Ethernet driver v1.3 (Mar 22, 2004)
8139cp 0000:00:03.0: PCI INT A -> Link[LNKC] -> GSI 11 (level, high) -> IRQ 11
8139cp 0000:00:03.0: PCI INT A disabled
8139cp: probe of 0000:00:03.0 failed with error -22

The PCI configuration looks like this (with an older working kernel)
