Public bug reported:
Binary package hint: network-manager
Hello,
This has started to happen to me the last couple of days. I'm running an
up-to-date Gutsy on a lenovo 300 n100 0768FPG. Sometimes, after resuming
from suspend, one CPU is throttled to 100% by networkmanager and
networking fails.
I get this error in deamons.log:

'TIMEOUT[CLI]'
