Interfaces are somethings not detected after return from suspend

[Pedro Côrte-Real]

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.

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.

Sorry for the duplicate. I didn't find the original one when I searched.
