The only change that IMHO matters happened between v4.10 and v4.11-rc1 is this:

@@ -6276,8 +6274,8 @@ static int e1000e_pm_freeze(struct device *dev)
                /* Quiesce the device without resetting the hardware */
                e1000e_down(adapter, false);
                e1000_free_irq(adapter);
+               e1000e_reset_interrupt_capability(adapter);
        }
-       e1000e_reset_interrupt_capability(adapter);

So, it apparently misses something for the other case, like
pci_disable_msi() call or so.

P.S. I'm not PCI or e1000e guy :-)
