nThis:


After registration of network interfaces the corresponding hotplug events are
triggered to early sometimes. This happens mostly when the system is under high
load; for example at boot time.

The problem with that is that udev cannot process its rules properly if some
attributes from sysfs are not available. When i investigated this problem the
sysfs files were already there but reading them did not work (e.g.
/sys/clas/net/eth*/address seemed to be empty)

Sometimes when ..../address could be read properly (and udev did the right
things), then rename_netiface could not rename the interface. Repeatedly trying
to rename it in a loop was succesfully after some time (far below 1 second).

See bug 230213 for the problems arising from this.

This is a regression since it did not happen on 10.1 or older. (not tested
explicitely, but i only got several reports for 10.2 and not for other
products.)
