Startup config sometimes fails to load (tested on x86_64)

[mattiaswal]

Running the test case/ietf-hardware/usb.py in a loop (with kvm disabled), i noticed that sometimes it booted with failure config, 1 of 22 tests.

The USB tests remove the configured USB ports, copy ru st, reboot the unit. So should have nothing to do with USB, since the startup configuration has it removed.
