It is known that original 11netcfg hook from pm-utils package doesn't work with netcfg daemons: net-profiles, net-auto-wired and net-auto-wireless. This problem can be solved partly by using 11netcfg from netcfg git. But there are following problems in it:

1. pmfunctions stopservice and restartservice are used to run/stop daemons. Actually these two functions should consider the current state of a daemon: function restartservice starts some daemon only in the case if a daemon was running and was stopped by stopservice function before. But there is a bug in stopservice function and it considers that any existent daemon is running now. As a result, after a resume from standby all netcfg daemons are started and it doesn't depend on their condition before suspend.

2. 11netcfg from git works only in binary mode: whether with daemons, or with manually started profiles (environment variable NETCFG_SUSPEND is responsible for this). I'm not a guru in netcfg, but I think that behavior for both variants can be combined, if correct sequence of run/stop of demons and suspend of manual profiles are used.

There is a patch in attach that fixes first issue and may fix the second.

P.S. I also have a minor patch for a file /usr/lib/pm-utils/bin/service from pm-utils package, which is responsible for the error in the stopservice function. But this is upstream bug and last changing of pm-utils git was done 9 month ago... Could someone from community say me, where I can upload a patch for its faster implementation in pm-utils?
This task depends upon

Hmm, what do you mean by does not work? For me, net-profiles suspend and resume correctly with 2.6.7...

If you mean original 11netcfg from pm_utils, it works only with active profiles and knows nothing about auto daemons (I consider net-profiles to be auto daemon too, because you can use it not only during boot; restart of this daemon will cause сonsistence enumeration of specified profiles).

Thus, original 11netcfg saves all ACTIVE profiles by calling "netcfg all-suspend" before suspend. After resume this script tries to reconnect saved profiles by calling "netcfg all-resume". Another NOT SAVED profiles will not be tried at all.

If you work in various environments with different profiles this is not your way (it will no automatic profiles switching).
