Hi, same problem here on a Samsung P35, ipw2200 and 8139too. I tried
several priorities for scripts in /etc/acpi/{suspend.d,resume.d}. It
isn't necessary to stop Networkmanager, but use
/usr/bin/dbus-send --system \
--dest=org.freedesktop.NetworkManager \
--type=method_call \
/org/freedesktop/NetworkManager \
org.freedesktop.NetworkManager.sleep
and .wake instead of .sleep. As far I can see it's see, it's a timing problem.
I tried to wake up nm before and after ifup, but it didn't work for me - only
after logging in.
I noticed, after resume both devices are still down and not shown by ifconfig.
resume from s2ram works for me - resume from s2disk not!
Hope that helps ...
