I can try that, though it seems to take a while to reproduce.  But I did
manage to find some useful data in syslog this most recent time:

Mar 29 01:19:47 leaf NetworkManager[3000]: <info> sleep requested (sleeping: no  enabled: yes)
Mar 29 01:19:47 leaf NetworkManager[3000]: <info> sleeping or disabling...
Mar 29 01:19:47 leaf NetworkManager[3000]: <info> (eth0): device state change: unavailable -> unmanaged (reason 'sleeping') [20 10 37]
Mar 29 01:19:47 leaf NetworkManager[3000]: <info> (eth0): cleaning up...
Mar 29 01:19:47 leaf NetworkManager[3000]: <info> (eth0): taking down device.
Mar 29 01:19:47 leaf NetworkManager[3000]: <info> NetworkManager state is now ASLEEP
Mar 29 01:19:47 leaf NetworkManager[3000]: <info> (wlan0): device state change: activated -> unmanaged (reason 'sleeping') [100 10 37]
Mar 29 01:19:47 leaf NetworkManager[3000]: <info> (wlan0): deactivating device (reason 'sleeping') [37]
Mar 29 01:19:48 leaf NetworkManager[3000]: <info> (wlan0): canceled DHCP transaction, DHCP client pid 3032

Does that help?  I don't see what *caused* NetworkManager to think it was OK to
sleep, but more importantly there doesn't seem to be any way to wake it up once
it has done so.
