Personally I don't think that this is coming from the kernel, because I reproduced it with older kernels. If this had been the case the bug would show up before upgrading to 13.10.  
About the bug, I'm experiencing exactly the same thing as Vladimir. I can add that for me the workaround works for not more than two times, after that, on resuming from sleep, the network-manager remains in sleep state, and the restart/shutdown functionalities are gone.

Title:
  Network does not come up after resuming from suspend.

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  When my computer wakes up from being suspended, the wireless network connection doesn't come back up.
  I'm able to fix the problem by running "nmcli nm sleep false", which causes the wireless card to reconnect.
