Same problem. Disabling sleep would likely fix it since it is a 0x9F DRIVER_POWER_STATE_FAILURE crash. A 0x9F DRIVER_POWER_STATE_FAILURE crash means that the system tried to enter a sleep or hibernation state (or tried to resume from one), and the driver did not respond to the request for the device to enter a low-power or disabled state (or enter a normal or enabled state for resuming from sleep/hibernation). In this case, your Intel(R) PRO/1000 PCI Express Network Connection Driver is not responding to the system's signal to change power states.
The other time you may see these crashes is when the system is shutting down to power down or starting up after being powered down.
