Linux newbie here- when asked in mailinglist what to do- was sent to file a bug
here. did a sarch and didn't find anything. Hoping that I am not making a fool
out of myself...
It would be interesting what the output of the commands
before and after a sleep/wakeup look like.
I suspect it's an initscript and/or hotplug problem rather than a net-tools one.

The result of the commands before sleep (good network)
Created attachment 89760 [details]
the result after sleep- dead network
Hm, looks really like hotplug doesn't reactivate the interface after
wakeup, e.g. that the kernel might not even get a hotplug event from
the laptop resp it's network card.
This can happen on some laptops, and unfortunately the only solution
for now is to restart the network manually via
service network restart
from a root shell.
Hope that helps,
