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,
