This happens to me all the time with the stock NetworkManager in edgy
and feisty. The cause seems to be:
Jan 23 04:51:13 localhost NetworkManager: <WARNING>^I nm_add_initial_devices
(): could not find existing networking devices:
The maximum number of pending replies per connection has been reached
** Changed in: network-manager (Ubuntu)
Importance: Medium => High
Status: Needs Info => Confirmed
** Summary changed:
- NetworkManager can't find interface on resume from Suspend after update 19 may
+ NetworkManager can't find interface on resume from suspend
** Description changed:
Problem with NetworkManager, not nm-applet, but NetworkManager didn't
appear in the package list - When suspending to RAM, NetworkManager
shuts down connection prior to suspend. After the latest update,
NetworkManger consistently crashes on resume from suspend, and gives the
error "No network devices can be found" despite the device functioning
perfectly. Killing
/usr/local/sbin/NetworkManager
required a -9 before it would die. Upon its death, running (as root)
NetworkManager then restarting nm-applet worked to restart.
+
Note: the original reporter indicated the bug was in package 'nm-
applet'; however, that package was not published in Ubuntu.
