I didn't look enough on this issue before. After resume, I get "invalid argument" from /sys/class/net/eth1/carrier. Reloading the driver *OR* restarting networkmanager solves the problem! Is it possible a process like nm blocks some ressources, which are re-initialised by reloading the driver or restarting nm? Notice, that just stopping nm is not enough. Thanks in advance, Nikolaus
