Or maybe the device got powered off somehow. If you've figured out a way to reproduce this more reliably, it might be interesting to do "echo on > /sys/bus/pci/devices/0000:03:00.0/power/control" and see whether it makes a difference. That should prevent us from using runtime power management for the iwlwifi device. Bjorn
