The original werks 10534 (1.6.0p11) and 11229 (1.6.0p16) tried to fix the following situation:

The "Check_MK discovery" check was unable to discover entirely new check_types. The discovery phase always relies on cached data, if available. Since the SNMP datasource only fetches the data it actually needs, there is no guarantee that all services will be discovered.

So the "Check_MK discovery" service failed to discover any interfaces, if the snmp host did not have any interfaces beforehand. Through WATO however, the discovery was successfull, since this mechanism may bypass the snmp caching entirely.

We have to revert these werk because they did not have the effect to fix above situation. In one of the next patch releases we will really fix this behaviour. Sorry for that.. :(
