Public bug reported:
Binary package hint: network-manager
Sometimes after returning from suspend network manager says it has no
detected interfaces. Here's what the log says:
Aug 25 12:12:25 localhost NetworkManager: <information>^IWaking up from sleep.
Aug 25 12:12:25 localhost NetworkManager: <information>^IDeactivating device
eth0.
Aug 25 12:12:25 localhost NetworkManager: <information>^IDeactivating device
ath0.
Aug 25 12:12:27 localhost NetworkManager: <WARNING>^I
nm_device_802_11_wireless_get_mode (): error getting card mode on ath0: No such
device
These are the first messages in daemon.log after suspend. If I disable
and then reenable networking network manager works again.

Aug 25 12:20:10 localhost NetworkManager: <information>^IActivation (eth0)
started...
After this the normal connection happens.
I suspect this happens because when network manager wakes up from sleep
the interfaces aren't available yet.
This is on an Apple White Macbook, with a 2Ghz intel core duo processor.
The network cards use the sky (wired) and ath (wireless) drivers.
