[Bug 1181777] Re: kvm: freeze a guest with a NIC PCI passthrough

[Pierre Schweitzer]

This workaround unfortunately appear to totally break the network card
in the VM making it unusable. TG3 driver (which is supposed to handle
it) cannot properly communicate with it.

The kernel outputs the following lines:
Jul 30 13:32:03 carrier-commander kernel: [    0.981658] tg3 0000:00:05.0: PCI INT B -> Link[LNKB] -> GSI 10 (level, high) -> IRQ 10
Jul 30 13:32:03 carrier-commander kernel: [    0.981722] tg3 0000:00:05.0: setting latency timer to 64

Jul 30 13:32:03 carrier-commander kernel: [    0.993954] tg3 0000:00:05.0: Problem fetching invariants of chip, aborting
Jul 30 13:32:03 carrier-commander kernel: [    1.047883] tg3 0000:00:05.0: Refused to change power state, currently in D0
Jul 30 13:32:03 carrier-commander kernel: [    1.047916] tg3 0000:00:05.0: PCI INT B disabled

The weird thing being this "-19" error, ie, -ENODEV.
